Abstract

Abstract: Based on the discrete event-triggered communication scheme (DETCS), the co-design between robust H_∞ guaranteed cost fault-tolerant control and communication was studied for uncertain nonlinear networked control system (NNCS) with actuator failures. Firstly, a new closed-loop failure model was established by introducing the DETCS and adopting state feedback control strategy. Then, based on the Lyapunov stability theory and less-conservative technology, the sufficient condition of NNCS with robust H_∞ guaranteed cost was derived, which was the time-delay/event-dependent approach, moreover, some optimal co-design methods between the fault tolerant controller and event-triggered weight matrix were given. Furthermore, the co-design problems of fault-tolerant control and discrete event-triggered communication were discussed under different index constraints. Finally, a simulation example illustrates the effectiveness of the proposed approach.
