In this paper, the passivity-based event-triggered fault tolerant control is investigated for networked control nonlinear systems subject to actuator failures under the DoS attacks. Firstly a switched system model is established for networked control systems under event-triggered sampling scheme, and the fault tolerant control is considered for networked control systems(NCSs) under the given actuator failures model. In addition, a new period event-triggered sampling approach was employed, and sufficient conditions are established to ensure the exponential stability, but also ensure strictly passivity for a prescribed passive performance based on the minimal sleeping time of DoS occurring condition. Finally, a simulation result is given to illustrate the effectiveness of the proposed methods.

本文针对在DoS攻击下受到执行器故障的网络控制非线性系统，研究了基于无源事件触发的容错控制。首先建立了事件触发采样方案下网络控制系统的切换系统模型，并在给定的执行器故障模型下考虑了网络控制系统的容错控制。此外，采用了一种新的事件触发的采样方法，并建立了充分的条件以确保指数稳定性，但也基于DoS发生条件的最短睡眠时间，确保对指定的被动性能严格被动。最后，给出了仿真结果，说明了所提方法的有效性。
