| Abstract: | Through approximation with a T-S fuzzy dynamical model, the nonlinear system is fuzzified into a local linear model. A variable structure controller is designed by using Lyapunov theory to assure the stability of the global T-S fuzzy model. It is used in stability controll of two chaotic systems, i.e. Lorenz chaotic system and Rossler chaotic system and the effectiveness of the scheme is proven through simulation. A good stability is achieved, without changing the inner structure of the system being controlled. The fuzzy controller is simple, practicable and involves fewer rules. |
