英文摘要	Based on discrete event-triggered communication scheme (DETCS) with sparse transmission characteristic and Takagi-Sugeno fuzzy method, the problem of robust H∞fault-tolerant event-triggered control is investigated for nonlinear networked control systems(NNCS) with actuator failure and actuator saturation. Firstly, a new fuzzy closed-loop fault model with actuator saturation is established under the background of sparse data transmission. Secondly, based on Lyapunov-Krasovskii stability theory, a sufficient condition is derived for NNCS with α-safety degree and disturbance rejection performance, which is the contractively invariant set of fault-tolerance with α-safety degree. And the integrated method between robust H∞fault-tolerant controller and event-triggered matrices is given out by linear matrix inequality (LMI) under event-triggered sparse data transmission. Lastly, the simulation example demonstrates the effectiveness of the method proposed. Furthermore, the study of compatibility analysis among disturbance rejection level, safety degree and network communication resource occupancy is also presented. © 2017 IEEE.
