Abstract: Aimed at a class of singular Markov jump system with mode-dependent time-varying input time delay and state delay, its robust H fault-tolerant control problem was studied when actuator failure took place. Based on integral-inequality method, the sufficient condition of existence of robust H fault-tolerant control regularity ofmemory-less state feedback in such system was given by means of constructing Lyapunov-Krasovskii functional, and the robust H fault-tolerant controller was designed to make the closed-loop system stable and satisfactory to certain H interference inhibitation level. Finally, the effectiveness of the proposed method was verified by a simulation example.

Key words: singular Markov jump system, uncertainty, mode dependence, robust H fault-tolerant control
