A Kind of Fuzzy Variable Structure Controller Design for Chaotic System
Tingzhi Ren · Acta Simulata Systematica Sinica · 2003
The problem of controlling chaotic Chua circuit has been studied. Using T-S fuzzy model as an approximation for nonlinear chaotic system, the nonlinear chaotic system has been fuzzilized into local linear model. The variable structure controller that is designed by using Lyapunov theory insures the stability of fuzzy dynamic system. The effect of the scheme has been tested by simulation. The fuzzy controller is simple, and needs no much rules.
