Title of the Paper: A practical Solution for the Classification in Interval-Valued Information systems

Abstract: Complex information systems have to manage enormous quantity of data, representing different measurements or attributes from various sources. Classification of this set of data is a difficult task that frequently requires special methods for being solved. The problem of classification in information systems has been studied by many authors, and different methods have been developed. The use of rough sets, fuzzy logic, neural networks, entropy, or the combination of these methods has been used widely. When information is diffuse and the number of obtained values for each attribute is large, so is the number of rules obtained for the classification. Even worst is hidden information in the data that makes the process complicated. Due to this fact, an interval of values is defined for each attribute, moving from the minimum to the maximum obtained values in the collected database. This is what is defined as interval-valued information systems. Differently from other wo!
rks, the concept of information measure is used in this paper, together with a fuzzy logic discrimination tool. Using these concepts, initially an attribute reduction is obtained and then fuzzy logic is applied for discriminating among the possible solutions. This method is simpler than others, and provides accuracy not less than the usually employed methods.

Abstract: In this contribution we present a development of a system for dimensional nanometrology based on scanning probe microscopy techniques (primarily atomic force microscopy, AFM) for detection of sample profile combined with interferometer controlled positioning. The key goal for introduction of interferometer measurement is not only improvement of resolution but the direct traceability to the primary etalon of length. Interferometry compared to a host of other optical length measuring techniques [1,2,3...] represents the most precise measuring technique available. The system is being developed to operate at and in cooperation with the Czech metrology institute for calibration purposes and nanometrology.

Abstract: In this work the authors present a mobile robot architecture design for real time autonomous navigation considering minimum requirements of hardware and computation. These requirements determine the use of simple sensors and minimum representation of the environment. The approach chosen was Behavior-Based for the design of the architecture and the behaviors. It is implemented under simulation of a differential wheels robot inside a 2D environment with a layout very close to a real situation for laboratories, offices and class-rooms. The solution takes into consideration local and long run navigation. A first approach utilizes only reac-tive behaviors, solving very well local navigation. It also gives a partial solution to long run navigation in a simple environment, with only two rooms, doing it without path definition. A complete solution for an envi-ronment with many rooms is developed adding to the previous approach more behaviors that will take care of path def!
inition and control. A linear graph, having the passages as landmarks, structures the environment repre-sentation and is the basis for the algorithm of path definition that gives an efficient solution. The architecture has not a central planner and controller as in traditional deliberative architectures; planning and control arises from the independent parallel functioning of all the behaviors. The results demonstrate that the design achieved its objectives and some important points to improve it are shown.

Abstract: This paper presents a controller design method for multi-input multi-output (MIMO) nonlinear time-varying systems using Radial Basis Funtion (RBF) neural network. The developed neuro-controller generates optimal control signals abiding by constraints, if any, on the control signal or on the system output. The proposed controller does not require an explicit knowledge of the states of the system or any apriori knowledge of the structure of nonlinearity of the system. Time based variations in system parameters as well as system nonlinearities are successfully compensated by the neural network. Simulation results for nonlinear time-varying systems are included at the end and controller performance is analyzed.

Abstract: In force controlled industrial robots, haptic and telemanipulation devices stability and control performance are contradicting requirements. In distributed systems where the sensors, actuators and control logic are separated in space, due to the network delays the control process may become unstable. In our research, we consider the coupled impedance type control algorithms as common used method in telemanipulation and interaction control of robots. In this paper, an extended TP model transformation is proposed to convert the delayed system into a polytopic tensor product (TP) model considering the value of the feedback delay as a parameter. Using such model, controller design become tractable as it does not contain feedback delay. A numerical example for a single degree of freedom impedance model with feedback delay is discussed. The results are confirmed by simulation.

Abstract: This paper deals with the topic of qLPV state-space model based control design in which LMIs are used to optimize the multi-objective control performance. In this paper we investigate how the manipulation convex hull of the polytopic model influences the control performance which is derived by LMIs. We examine these influences through the control design of the two dimensional aeroelastic system’s example. First we define various TP type polytopic model representations of a wing section whose vertices define different convex hulls. In the second step we investigate how these models lead to different control performances.

Abstract: Measurement with nanometer resolution is required for the next advance in nanotechnology. Especially the non contacting methods of measurement are very .promising. We present the set-up of the laser interferometer with nanometer resolution. We developed three types of laser sources especially for using in laser interferometry and absolute laser interferometry. The standard He-Ne laser source for conventional laser interferometry techniques can be replaced by one of these tree types of laser sources. We used Vertical Surface Emitting Laser (VCSEL) and Distributed Feed-Back (DFB) laser diodes to design these laser sources. For these laser diodes we developed several methods to improvement their wavelength stability and tunability by fiber Bragg gratings (FBGs). We developed simulation method to calculation of arbitrary fiber grating (apodized, chirp etc.) with high precision by combination of methods based on layered dielectric media (LDM) and transfer matrix. On the!
basis of our simulations and measurements of the commercially available fiber gratings we designed a special 100 mm long fiber Bragg grating with apodization. We expect the application of the FBG to improvement of the linewidth and mode-hop free tuning range of semiconductor lasers at the wavelength 760 nm to increase resolution of fiber laser interferometer based on these diodes. We built the absolute fiber laser interferometer with Vertical Cavity Surface Emitting Laser (VCSEL) to easy employ FBG to stabilize wavelength and control the tuning range. First set up is presented.

Abstract: With the rapid development of networks and computer technology, there is a growing need for the network to support a variety of services with different quality of service (QoS). Differentiated services (DiffServ) is the proper technique to deal with various QoS needs. In this paper, we study realization mechanism of QoS DiffServe model based on network processors (NPs), and propose a new packet classification algorithm called classification based on network processors (CBNPs). This CBNPs algorithm uses parallel tuple search and multi-threaded concurrency of NPs to enhance the classification speed, and also has less space and time complexity than other parallel algorithms. The simulation result shows that CBNPs is high-speed, multidimensional and scalable, and its com-prehensive performance is much better than that of the existing packet classification algorithms.

Abstract: Total quality management is from a decade an important and useful organizational system for increasing companies' competitiveness, by optimizing processes with a particular focus on the customer. Among all the methodologies, ISO 9000 certification is one of the most common and recognized approaches for the benefits of the companies that decide to implement it. Several studies have been conducted in literature, presenting some important impacts of the ISO 9000 on the companies' performances. Due to the vast number of works, a classification of the main impacts of ISO 9000 on the principle business performances is needed. The findings coming from the literature review analysis are therefore validated through a survey extended at 366 companies. The resulting information of the investigation are coherent with those studied in literature, even if some key aspects are extremely focused on a restricted set of impact areas. The investigation allow the author to identify th!
e main impacting dimensions of ISO 9000 on the performances of the companies. Moreover the barriers and pitfalls for a successful ISO 9000 certification are presented, furnishing details for overcome these issues.

Abstract: Abstract: - Six Sigma (SS) methodology is nowadays one of the most used approaches in the Quality Management field since its benefits, coming from the improvement of the process outputs quality by identifying and removing the causes of defects and variability in manufacturing and business processes. Thus, literature on the SS topic is exponentially increased during last decades; the vast number of works on the SS field represents a good opportunity for a structured literature review of the articles, in order to understand the evolutions of the concept, the fields of its application and possible evolution for further studies. The literature review has been carried out by using a chronological review of the main SS approaches developed both for large and small companies, in order to highlight particular aspects of the SS literature and some applications of the SS methodology. The evaluation of the papers found in literature is carried out through a Strengths-Weakness!
es criterion. Moreover, for those treating the application of the SS methodology into both big companies both Small & Medium Enterprises (SMEs), an assessment has been carried out based on the accordance with some milestones identified as necessary for every SS system. Finally the paper argues the possible further developments of the research field.

Title of the Paper: Analysis of Traffic Noise in a Road Intersection Configuration

Email addresses of all the authors: guarnaccia@sa.infn.it
Number of paper pages: 10
Abstract: Acoustical noise produced by vehicular traffic depends on many parameters, including the geometry and the general features of the road. The presence of a conflicting point, i.e. an intersection, strongly affects and modifies the simulation strategy of noise in urban environments, that is usually performed with statistical models tuned on experimental data related to standard condition (free flow traffic, intermediate vehicular volumes, etc.). In this paper, the author presents the analysis of an intersection case study in proximity of Salerno University, performed by means of experimental measurements and software simulations. The chosen area presents interesting features because of the priority rights on the principal road and because of the relevant amount of vehicles and buses, mainly due to the University students and personnel that transit in the intersection, especially during rush hours. The aid of a predictive software is highlighted, together with the shor!
tcomings of a simulation strategy that does not take into account traffic dynamics. The analogy between electrical current and vehicular flow is sketched and used in the roads vehicles volume definition.

Abstract: The FAMEtool is a support tool for the FAME (Filter, Analyze, Measure and Evaluate) Methodology, an iterative approach for open source software assessment. The FAMEtool does not replace evaluation experts, but it serves to improve the productivity of experts in evaluating the different solutions. The efficacy of the FAMEtool is reported in this paper. Several methods have been created to define a process for assessing Free/Open Source software. Some focus on some aspects like the maturity, the durability and the strategy of the organization around the Open Source project itself. Other methodologies add functional aspects to the assessment process. Only some of these methodologies are supported by specific tools. This paper describes the FAMEtool that implements the steps of the FAME methodology, particularly in the filtering and analysis phases, trying to follow the logic of the simplified method that allows a faster application and gives support to who will be eng!
aged in the selection of the new IT solution. Such a tool is introduced in the form of Web application and has been developed in Java.
Keywords: Open Source software, Software evaluation, Technology transfer, Software quality, Assessment model.

Abstract: Recent study shows that fetal chromosomal abnormalities can be detected in early ultrasonic prenatal screening by identifying the absence of fetus nasal bone. The drawbacks of current method are operator dependent, observer variability and improper training. In particular, accurate nasal bone detection requires highly trained sonographers, obstetricians and fetal medicine specialists since the ultrasound markers may easily confuse with noise and echogenic line in ultrasound image background. We present a computerized method of detecting the absence of nasal bone by using normalized grayscale cross correlation techniques. Image preprocessing is implemented prior to cross correlation to assess the availability of nasal bone. The resultant threshold, bordering the absence and presence of nasal bone, is set to a value of 0.35. The accuracy of the developed algorithm achieved was, around 96.26 percent which promises an efficient method to recognize nasal bone automatic!
ally. The threshold can be further improved if a larger set of nasal bone ultrasound images are applied.

Email addresses of all the authors: danacrst@yahoo.com
Number of paper pages: 10
Abstract: In this work we survey our research on domain decomposition and related algorithms for large power electric cables and the impact on the human health. The equations that describe the behaviour of the fields in electromagnetic devices are coupled because most of the material properties are temperature dependent and may depend on temperature in a nonlinear way. More, any power loss is transformed in local heating so that the heat source in the thermal model is the Joule-Lenz effect of the electrical current. Here we assume that the sources of the magnetic field have sinusoidal time dependence and we neglect the effects due to the displacement currents. The target example is from the electric engineering. It is a large power cable in a free space. General symmetry of the device can be used for efficient software. The algorithms for analysis are presented in the context of the finite element method. The results can be extended for simulation of distributed-parameter s!
ystems described by elliptic and parabolic equations. The domain decomposition at the level of the problem is used. In this way the coupled magneto-thermal problem can be analyzed by a reduction of the computational effort.

Abstract: This paper deals with a testing method suitable for SIP infrastructure. The performance testing is an issue of research and no standardized methodology has been adopted yet. We present the main ideas of the methodology that allows for testing the keystone of SIP based infrastructure – the SIP Server – in both SIP Proxy and B2BUA (Back to Back User Agent) configurations. Our methodology has its foundations in the work of the IT Company Transnexus and these foundations have been enhanced with the ideas reflecting the nature of the SIP protocol. In addition, the entirely new methodology for benchmarking the SIP server in the B2BUA configuration has been introduced. This method utilizes one of the attributes of the B2BUA – the flow of media passing through the B2BUA – and measures the effectiveness of codec translation, which relates to the performance measured in cases without codec translation. Our approach offers the complex method for testing SIP infrastructure, wh!
ich has been verified experimentally. The out-coming results are the part of this paper together with appropriate comments and conclusions.

Abstract: Artificial intelligent techniques have been widely used in high voltage insulation technology application. In this paper, the effectiveness of artificial intelligent technique to apply for pattern recognition and classification of Partial Discharge (PD) is presented. Partial discharge signal was generated and measured by using an artificial partial discharge source. Characteristics of PD signal for pattern recognition and classification were determined by using statistical and fractal methods from relationship among the voltage phase angle, the discharge magnitude and the repeated existing of partial discharges. The simplified fuzzy ARTMAP (SFAM) was used as artificial intelligent technique for pattern recognition and classification. PDs characteristic quantities were used as input parameters for Simplified Fuzzy ARTMAP to train pattern recognition and classification system. Pattern recognition and classification results were obtained. The results demonstrated the !
high effectiveness of the purpose technique applied for pattern recognition and classification of partial discharge.

Abstract: The gripper is one critical component of an industrial robot which is often useful in industrial environments for object grasping during handling process. In this paper, a gripper is designed and implemented to grasp unknown objects with different masses, dimensions, and coefficients of frictions considering simplicity, wide range of objects and economy. The proposed grasping process during object lifting and handling is mainly based on the slip reflex principle, as applying insufficient force leads to object slipping, and dropping may occur. In the mean time, applying extra force during grasping may lead to object crushing. A new scheme system controller using fuzzy systems based on empirical investigation of the human hand skills is proposed to control the applied force on the object without the risk of object crushing or dropping. Adaptive neuro-fuzzy inference system ANFIS is used to model the assigned robotic gripper based on input/output variables measurement!
s. Reducing the distance of the slippage and process time can be achieved owing to the proposed robotic gripper as shown in experimental results.

Abstract: Unified Smart Classification Algorithm (USCA) for the purpose of data processing and classification of data obtained from different testing techniques is designed and tested. The developed algorithm conditions data taken from damaged composite structures such as modern car bodies and Plane frame structure. It is used in conjunction with a Modified Weight Elimination Neural Networks Algorithm (MWEA) to provide predictive models for impact damage in composite structures. The developed neural models correlated between various NDT testing techniques, such that in the absence of one technique, its results are predicted by the Neural Network through interrogation of available data obtained using other testing methods. The real and predicted data showed good agreements in terms of classification and prediction.

Abstract: This paper presents a QoS (Quality of Service) based selection and composition model for semantic web services in which the negotiation is performed with all the discovered service providers and the negotiation results are used in the selection process. In semantic web service composition, the selection can also be performed after negotiating with all the discovered service providers and the negotiation-agreements generated from the negotiation can also be used in the selection process. This paper presents a semantic web service selection and composition model based upon this concept. In this paper, a multi-agent negotiation based semantic web service composition approach has been presented. A negotiation agreement based selection model has also been presented that uses the assessment of the various quality parameters included in the negotiation agreement for rating the service provider agents. The implementation issues in the work has been discussed and the compar!
ative analysis has been performed.

Title of the Paper: Excision of Pulmonary Nodules or Masses in Patients with Known Malignancies through Video-Assisted Thoracoscopic (VATS) Surgery

Abstract: Introduction. The development of computed tomography (CT) have made more pulmonary nodules being found in patients with known malignancies during work-up or follow-up. Excision through video-assisted thoracoscopic surgery (VATS) can be applied as a reliable method for the diagnosis and treatment of these nodules. Patients and Methods. From July 1996 to June 2009, 78 patients with newly diagnosed or prior treated malignancies were found with indeterminate pulmonary nodules or masses which were excised through VATS. Forty-three males and thirty-five females were included with ages ranging from 14 to 88 (median: 61) years. Their known malignancies arose from the colo-rectal (26 patients), breast (17 patients), head and neck (10 patients), lung (8 patients), soft tissue sarcoma (6 patients) and others (12 patients). Since July 2001, CT-guided localization before VATS was used in 13 patients with small (<10mm) or deep (>5mm) pulmonary nodules. All the visible tumors !
were resected in patients undergoing this procedure for treatment. However, only one to two nodules were removed in patients for confirming diagnosis. Results: The resected tumor size ranged from 0.2cm to 6.5cm (Median: 1.5 cm) and the number of the resected tumors ranged from 1 to 5. All lesions were successfully resected through VATS. There were 52 of them undergoing this procedure for diagnosis and treatment (including malignant and benign lesions) and 26 of them for diagnosis only. The indication of the use of pre-operative CT guided localization included small lesion in 2, deep seated lesion in 3, both small an deep seated lesion in 6 and dense adhesion which can be predicted by prior intrathoracic radiation or operation history in 2 patients. Among these 78 patients, metastatic malignancies were diagnosed in 43 of them, 8 of them were secondary primary pulmonary neoplasms, and 27 of them were benign lesions (20 of them were granuloma with or without evidence of tub!
erculi infection). Subsequent conversion to open procedure (a utility
incision from 4 to 11cm) was performed in 6 of the 8 patients with second primary lung carcinoma and 6 patients with the size of metastatic tumors larger than 3 cm in diameter. The median length of chest tube indwelling was 4 days. Over 90% (71/78) of patients can return to normal daily activity within 14 days. Conclusion: Resection of pulmonary nodules or masses through VATS for patients with prior or at present malignancies can be helpful in their early and reliable diagnosis as well as minimally invasive and effective treatment. Pre-operative CT-guided localization can facilitate subsequent resection and avoid possible open procedures.

Abstract: This paper presents the effect of the output capacitor on the EMI spectrum of radiation, the output voltage ripple and the efficiency of a SEPIC Converter. Two SEPIC converters were designed with LT1871 (Linear Technology) and LM2577 (National Semiconductor), for an input voltage of 4 to 16V, the output voltage of 5V, output current of 0.5A, and the switching frequency of 52kHz. The functionality of the converter was simulated in LTspice IV and OrCAD, and it was compared with the experimental results. It was measured the level of EMI spectrum, the output voltage ripple and the efficiency of the converter with different types of capacitors. An acceptable output voltage ripple, which respects the standards FCC Class A and Class B, was obtained with solid and tantalum capacitors in parallel with small MLCC capacitors. The minimum of ripple and frequency spectrum was obtained by adding a LC Filter to the output of the converter. With this filter the converter respects !
the standard SAE J1113.

Abstract: We propose the use of a new implementation of the hyperanalytic wavelet transform, (HWT), in association with a Maximum a Posteriori (MAP) filter named bishrink. The denoising methods based on wavelets are sensitive to the selection of the mother wavelets. Taking into account the drawbacks of the bishrink filter and the sensitivity with the selection of the mother wavelets we propose a denoising method in two stages in a multi-wavelet context. It is based on diversification followed by wavelet fusion. Some simulation examples and comparisons prove the performances of the proposed method.

Abstract: A new data association method is presented for target tracking. The proposed method is formulated using reverse prediction weighted neighbor to calculate probability of candidate measurements from targets. Comparing with NNDA, PDA and JPDA, which are widely applied in single or multiple targets tracking, the new method has a small computational complexity with acceptable miss-tracking probability and does not need priori knowledge such as detection probability and clutter density. The correlation probability between measurements and targets is reflected in the reverse prediction residual norm. Simulation results showed that the proposed method can track targets in a cluttered environment with good performance.

Abstract: Theoretically and generally, Down syndrome children in this study are defined as children who are proven scientifically and medically of their impairment in mental health or developmental abilities. Although some of the limitations of Down syndrome children cannot be overcome, early childhood intervention is proven to be able to improve the quality of their lives. Early childhood intervention includes screening for common problems, and vocational training can improve the development of the Down syndrome children. The language ability is emphasized in this study as the speech and language skill of Down syndrome children are significantly delayed – more delayed than non-verbal abilities. Besides that, the speech and language skill underpin social and cognitive development, therefore affecting all aspects of development. In other words, improving the language ability of individuals with Down syndrome will improve all aspects of their development and quality of lives. !
In this study, the support system provides the most effective assessment and training method for language ability to the children.

Abstract: This paper presents a Particle Swarm Optimization (PSO) based Model Predictive Control (MPC) scheme applied to Automatic Generation Control (AGC) systems. The proposed scheme formulates the MPC as an optimization problem and PSO is used to find its solution. Single area AGC model is taken incorporating Generation Rate Constraint (GRC) nonlinearities and constraints on the control input. Two interconnected area AGC system excluding nonlinearity is also studied. The simulation results draw several comparisons to preceding literature showing significant improvements and signifying the strengths of the proposed MPC scheme. Furthermore, performance of controller is also explored for varying power demands, different GRC values and parameter variations.

Abstract: Considering the unavoidable and unmeasured disturbances, parameter variations and position measure error of real motion control applications, a novel controller is developed for the motion control of permanent-magnet synchronous motors (PMSM). First, an active disturbance rejection controller (ADRC) based on extended state observer (ESO) is employed to ensure the high performance of the entire control system. The ESO estimate both the states and the disturbances so that the ADRC has a corresponding part to compensate for the disturbances. And then, the inertia of system is identified online to improve the performance. At last, considering the case of position measure error, which is commonly in the applications that an encoder is used for position detection, an asynchronous sampling method (ASM) is used. The ASM detects the position at the moment of actual encoder pulse input, thus eliminating encoder positioning error. Simulation and Experimental results are shown!
to verify the method.

Abstract: Three dimensional (3D) ultrasound image reconstruction based on two dimensional (2D) images has become a famous method for analyzing some anatomy related to abnormalities. 3D ultrasound image reconstruction system is required in order to view the specific part of the object and so that it can be used for analysis purpose. In this paper, 2D images of fetal phantom were taken by using untracked free-hand ultrasound system. Few sets of 2D images were taken with different number of slices and after some basic 2D image processing, 3D reconstruction is done by using surface rendering techniques by implementing contour filtering and marching cubes algorithm in Visual C++ 6.0 with Visualization Toolkit (VTK) toolbox. From the experiment, we can conclude that in order to reconstruct a better 3D image, the aid of tracking sensor is important. Besides, image processing need to be performed thoroughly by adding other detailed processing techniques so that noises can be fully r!
emoved. From the result also, it can be concluded that the marching cube algorithm can give a better result compare to contour filtering where marching cubes algorithm can generate higher intensity 3D image which can make user easy to detect inner part and edges of 3D images. The number of slices should also be increased to improve the accuracy of the 3D image constructed.

Abstract: In this work is presenting the study of the electric current's parameters and characteristics, obtained by means of an electric power's quality analyzer. Also, are analyzed the various possibilities of compensating the effects produced by the consumers, e.g. by the locomotives equipped with DC motors, in order to reduce the reactive power, the current harmonics or the voltage harmonics, respectively the reactive power and harmonics simmultaneously. The measurements were made into an AC railway electric traction substation of 27 kV, during more hours, being registered momentary and average values. The data acquired with the electric power's quality analyzer were registered into a computing system, for their further analysis. In order to achieve the adaption between the analyzer's input measures and the traction line's values, the measurements were made in the secondary of the voltage and current transformers existent in the traction substation.

Abstract: The RS-485 protocol is a Modbus serial communication, mainly used by SCADA(Supervisory Control And Data Acquisition). Most industrial infrastructure using this communication protocol is designed not to be exposed to an open network environment, seriously vulnerable to security threats. Therefore, this study examines key management architecture in order to suggest a key exchange algorithm suitable for the RS-485 protocol. The suggested algorithm can support both 1:1 and 1:N communications as well as minimize the amount of loads arising from encoding/decoding so as to increase its application.

Abstract: Since the researches on augmented reality have recently received attention, M2M market started to be activated and there are numerous efforts to apply this to the real life in all sectors of society. However, with the existing marker-based augmented reality technology, a designated object only can be loaded from one marker and one marker has to be added to load the same object additionally. To solve this problem, the relevant marker should be extracted and printed in screen so that loading of the multiple objects is enabled. However, since the distance between markers will not be measured in the process of detecting and copying markers, the markers can be overlapped and thus the objects would not be augmented. To solve this problem, a circle having the longest radius needs to be created from a focal point of a marker to be copied, so that no object is copied within the confines of the circle. Therefore, in this paper, multiple objects detection and loading using PP!
HT has been developed. And markers overlapping control according to multiple objects control has been studied using Bresenham and Mean Shift algorithm.

Abstract: RTD-A (Robustness Tracking Disturbance rejection-global Aggressiveness) controller, proposed by Babatunde A. Ogunnaike, is suitable for single input single output system (SISO). On the basis of it, a new RTD-A controller for Multiple Input Multiple Output system (MIMO) is illustrated and the global optimal control solution is also discussed in this paper. Simulation results prove that compared with IMC-PID (Internal Model Control), this new algorithm has good performances in set-point tracking, disturbance rejection and robustness.

Abstract: The grid codes now require doubly fed induction generator (DFIG) wind turbines having the ¡°low voltage ride-through (LVRT)¡± capability. However, a traditional DFIG with a partially rated back-to-back converter has inherent difficulties to ride through the grid faults, especially for the unbalanced grid faults. Modifications to the traditional DFIG configuration for ride-through have become necessary. A DFIG system with series grid-side converter (SGSC) has an excellent potential for voltage dips tolerance. This paper analyzes the reasons of a DFIG system with SGSC for ride-through and presents a control scheme for operation under unbalanced grid faults conditions. During grid faults, the each component of the generator¡¯s stator flux is effectively controlled through the SGSC. Also, the stator and rotor currents are further restricted by controlling the rotor-side converter (RSC) to reduce the absorbing energy from wind turbine. Then, successful ride-through of a!
DFIG system with SGSC under all types of severe unbalanced grid faults at the point of common coupling (PCC) are achieved with reduced electromagnetic torque oscillation. The proposed control scheme is validated by means of simulations.

Abstract: Power converters with their controls normally behave as a constant power load. This load can significantly degrade the system stability. Therefore, the system dynamic model is very importance because it can be used for stability analysis. It is well known that power converter models are time-varying because of their switching behaviours. This paper presents the DQ modeling method to eliminate the switching action to achieve time-invariant model for the stability analysis. The power system studied is the AC distribution system. The small-signal model of the power system is obtained by using a linearization technique. The small-signal simulations are used to validate the DQ linearized model. The reported model is then used for the stability analysis via the classical control theory. The results show that an excellent agreement between the mathematical model and the three-phase benchmark model is achieved.
