Abstract

A model of a kind of uncertain switched fuzzy systems is presented first, in which each subsystem is an uncertain fuzzy system. Then state feedback H_infin robust control of this class of systems is studied using switching technique and multiple Lyapunov function. A switching strategy of the switched fuzzy system with continuous controlled input is developed. The main condition is given in form of LMI which are more solvable. The elaborated illustrative examples and the respective simulation experiments demonstrate the effectiveness of the proposed method.
