This work studies the event-based fault-tolerant control issue of networked control systems with actuator saturation, resilient event-triggering, randomly occurring nonlinearities, and denial-of-service jamming attacks (DoS-JAs). Initially, we aim to design a resilient event-triggered (ET) communication scheme under the attacks, proposed by the known period of the jamming signal. The period values occur in uniform lower bounds for the jammer's sleeping time. Next, a closed-loop networked control system is constructed as a switched-control strategy subject to state-delay, in addition to actuator saturation, actuator faults, DoS jamming attack, parameter uncertainty and resilient ET control schemes. Based on the Lyapunov stability theory, piecewise property and Wirtinger-based integral inequality, a set of sufficient conditions are obtained to ensure that the resulting closed-loop switched system is exponentially stable against DoS jamming attacks and satisfies mixed and passivity performance index. Furthermore, the efficacy of the proposed method is demonstrated through simulated examples based on the two practical applications of satellite control systems and aircraft flight control systems.

具有随机发生的非线性和 DoS 攻击的网络控制系统的弹性事件触发容错控制

这项工作研究了具有执行器饱和、弹性事件触发、随机发生的非线性和拒绝服务干扰攻击 (DoS-JA) 的网络控制系统的基于事件的容错控制问题。最初，我们的目标是在已知干扰信号周期提出的攻击下设计一种弹性事件触发（ET）通信方案。周期值出现在干扰器休眠时间的统一下限中。接下来，除了执行器饱和、执行器故障、DoS 干扰攻击、参数不确定性和弹性 ET 控制方案之外，闭环网络控制系统被构建为受状态延迟影响的开关控制策略。基于李雅普诺夫稳定性理论、分段性质和基于维廷格的积分不等式，获得了一组充分条件，以确保所产生的闭环交换系统对 DoS 干扰攻击呈指数稳定，并满足混合和被动性能指标。此外，通过基于卫星控制系统和飞机飞行控制系统两个实际应用的模拟实例，证明了所提出方法的有效性。
