On robust fault-tolerant control of linear uncertain time-delay systems

Taking a linear uncertain time-delay system and introducing memoryless state feedback control law, the sufficient conditions for the closed-loop systems possessing robust fault-tolerant capability against the actuator faults or the sensor faults are obtained by using modified Lyapunov inequality. A state feedback controller can be obtained by solving a group of LMIs, and a more general continuous fault model than discrete fault model is also considered. At the end of this paper, a simulation example is given to illustrate the feasibility and effectiveness of the proposed approach.
