Abstract

Based on the T-S fuzzy model, output feedback reliable control problem is studied for a class of uncertain switched fuzzy models with controlled time delay, which is developed by combing the switched fuzzy system, output feedback control and reliable control together .When the actuators seriously faileduthe unexpired part can not stabilize the original system, the output feedback reliable controller and the suitable switching law switching in the non-failure part of the actuator are designed to make sure that the closed-loop systems are asymptotically stable for all allowed uncertainties. A sufficient condition for the form of inequality that keep the closed-loop systems uniformly asymptotically stable is given with the method of multi-Lyapunov. In the end, the state curve and control curve of the proposed systems are given by simulink simulation to illustrate the feasibility and effectiveness of the output feedback reliable control method.
