Abstract

In this paper, based on a class of T-S fuzzy systems with sensor fault and time delays, a fault-tolerant guaranteed cost control method is proposed. This method is on the premise of the system state observer, according to the fault estimate, establishes output feedback controller and determines fault-tolerant guaranteed cost controller, thus ensures that the closed-loop system is asymptotically stable and to have the appropriate performance index. Then uses LMI toolbox to solve the controller. Finally, simulation result of example shows the feasibility and effectiveness of this method.
