Robust reliable control for a class of uncertain switched fuzzy systems based on observers switching
It is presented a model of uncertain switched fuzzy systems, which each subsystem of switched system is an uncertain fuzzy system, and the robust reliable control problem is studied. When the actuators are serious failure - the residual part of actuators can not make original system stability, using switching technique depend on the states of observers and Lyapunov function method, dynamic fuzzy reliable controller is built to ensure the relevant closed-loop system is asymptotic stability. Moreover, observers switching strategy achieving observer errors decreasing uniformly asymptotically to zero of the uncertain switched fuzzy systems is given. A simulation shows the feasibility and the effectiveness of the method.
