摘要

This paper proposes an adaptive fault-tolerant control method for Markovian jump systems in the presence of actuator fault, unknown dead zone, and external disturbance. There is no prior knowledge of the exact model of the actuator fault. The uncertainty due to the actuator fault and unknown dead zone is tackled by the adaptive rules in the proposed control method. The actuator fault is assumed to be the partial loss of effectiveness. The stochastic stability of the entire system is assured through coupled linear matrix inequalities (LMIs) despite no prior knowledge of actuator fault, dead zone, and external disturbance. The simulation results have validated the merit and efficiency of this proposed control method.
