Abstract: This paper presents a new method to synchronize chaos in nonlinear systems. This new method is called Generalized Backstepping Method (GBM) because of its similarity to Backstepping Method (BM), but its more abilities to control nonlinear systems than it; such as wide range of controllable systems, better settling time, lower overshoot and etc. In paper chaos in Lorenz equations is selected as case study. This method has some coefficient that positively is only condition to select them. In papers this parameters are chosen optionally but optimal selection of this parameters help to receive best response of systems. In this study Genetic Algorithm (GA) is chosen to optimize these parameters. GA select best values for them by minimizing fitness function that defined to minimize error function. The results of simulations prove more abilities of GBM than many methods to decrease error.
