Abstract

Under the DETCS, this paper studied the off-line design on less conservative robust fault-tolerant controller and the active-passive fusion fault-tolerant control problem of its on-line active optimization choice for the NCS with severity differences of actuator failure. Firstly, it applied the concept of "partial order" to distinguish the severity of the fault. Secondly, it constructed the structural framework of active-passive fusion fault-tolerant control. Thirdly, based on the established model, for the four different severity fault modes sets such as normal、slight、moderate and heavy, this paper proposed an off-line design method of less conservative robust H∞ fault-tolerant controller set by constructing the Lyapunov-Krasovskii functional and used the improved Wirtinger inequality and mutual convex lemma and other techniques. Then, according to the severity of the fault diagnosis with on-line runtime, it optimized and switched the corresponding fault-tolerant controller based on the selection strategy of optimal performance and less switching. Finally, the feasibility and effectiveness of the proposed method were verified by simulation examples.
