Fuzzy controller design for Chua chaotic system--LMI method
Chua混沌系统的一种模糊控制器设计--LMI法

The problem of stable 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 fuzzy into local linear model. The controller designed by using Lyapunov theory insures the stability of fuzzy dynamic system. The parameter of fuzzy controller is got by convex optimal method of LMI. The effect of the scheme has been tasted by simulation. The Fuzzy controller is simple, and need no much rules.
