Fuzzy Control for a Class of Nonlinear System with Adaptive Fuzzy Supervisory Controller

When the nonlinear functions in the system are bounded but the bound functions are unknown, a fuzzy control equipped with adaptive fuzzy supervisory controller for a class of nonlinear system is presented. In this method, a fuzzy logic system is used to approximate unknown bound function, the supervisory controller is designed by the fuzzy logic system, and the unknown parameters in fuzzy logic system are adjusted adaptively. It is proved that this method can guarantee the bounded of the state of closed-system. Simulation results indicate the effectiveness of this method.
