Abstract: This paper presents on the application of the partial decoupling control for the nonlinear MIMO hydraulic plant composed of two tanks connected with each other. In order to make the plant more challenging for control the first tank has variable cross sectional area and there has been applied additional interaction for input flow streams. By means of the three port valves some fraction of the first flow stream (F1) is fed into the second tank and some fraction of the second flow stream (F2) is fed into the first tank resulting in the smaller relative degrees in the cross channels of the nonlinear plant. The goals of the control algorithm were maintenance of the both liquid levels (H1, H2) at preset values and elimination of the interactions between control loops. The application of the partial decoupling matrix of constant elements together with the DMC controller for the first tank and PI controller for the second tank (of constant cross sectional area) gave satisf!
actory results – smaller interactions between control loops. Moreover, it has been studied the quality of control in the presence of the additional disturbances for the system with active or non-active decoupling mechanism. The plant was disturbed by two oscillating sinusoidally with nonzero mean input flow streams (F3, F4) for the first and second tank respectively. The simulation results have shown that the decoupling mechanism improves quality of control in the presence of the disturbances.
