In this paper, a novel fault-tolerant control scheme is proposed for a class of uncertain switched systems with time-delay. The mathematical model of actuator which fault is established. Our attention is focused on the design of a sliding mode fault-tolerant controller, which guarantees the system to be asymptotically stable and has a H∞ disturbance attenuation performance in the case of actuator failure. Sufficient conditions for the existence of a desired sliding mode controller are established in terms of linear matrix inequalities (LMIs), and the corresponding sliding mode controller is designed. Simulation results verify the validity and feasibility of the proposed fault-tolerant control strategy.
