Abstract

Fuzzy guaranteed cost controller design method for uncertain chaotic system stability control is addressed. Uncertain chaotic system is expressed by T-S fuzzy model with polytopic uncertainty, and then sufficient condition for global T-S fuzzy system stability and solving algorithm for state feedback fuzzy guaranteed cost controller are given. Simulation is made for uncertain Lorenz chaotic system with fixed parameter or time-varying parameters, and simulation results show control system designed by the given method has good control performance and robust stability.
