英文摘要	Considering the actuator saturation and actuator failures, the co-design between network communication and robust fault-tolerant control is studied for the uncertain nonlinear networked control system (NNCS) with alpha-safety degree under the discrete event-triggered communication scheme (DETCS). Based on constructing the appropriate delay-dependent Lyapunov-Krasovskii function, the sufficient condition is derived to guarantee the asymptotic stability and alpha-safety degree of NNCS under DETCS, which is the contractively invariant set of fault-tolerant control with alpha-safety degree. Furthermore, the co-design method between robust fault-tolerant controller and event-triggered weight matrix is also proposed in this paper. Finally, the simulation experiment shows that the method described herein can not only make the closed-loop fault NNCS with actuator saturation possess a higher safety degree and a better dynamic performance, but also reduce communication load effectively.
