This paper studies event-triggered output feedback resilient control for networked control systems (NCSs) under stochastic deception attacks following a Bernoulli distribution. Unlike continuous event-triggered mechanism (ETM) requiring dedicated hardware and complex Zeno-avoidance computation, an output-based discrete ETM is firstly introduced, which overcomes limits of continuous ETM and relaxes state-available constraint. Secondly, a novel time-delay system model is established, which makes it possible to study effects of the ETM, stochastic attacks and network-induced delays in a unified framework. Thirdly, less-conservative asymptotic stability criteria with desired H ∞ index are obtained, which derive quantitative relationships among the ETM, stochastic attacks, network delays, plant and resilient controller. Further, sufficient conditions to co-deign the ETM and resilient controller are presented. Finally, examples confirm effectiveness of the proposed method.

欺骗攻击下 NCS 的事件触发输出反馈弹性控制

本文研究了在遵循伯努利分布的随机欺骗攻击下，网络控制系统 (NCS) 的事件触发输出反馈弹性控制。与需要专用硬件和复杂的 Zeno-avoidance 计算的连续事件触发机制 (ETM) 不同，首先引入了基于输出的离散 ETM，它克服了连续 ETM 的限制并放宽了状态可用约束。其次，建立了一个新的时延系统模型，使得在一个统一的框架内研究 ETM、随机攻击和网络引起的时延的影响成为可能。第三，获得了具有期望 H ∞ 指数的不太保守的渐近稳定性标准，它推导出 ETM、随机攻击、网络延迟、工厂和弹性控制器之间的定量关系。更多，提出了共同设计 ETM 和弹性控制器的充分条件。最后，实例证实了所提出方法的有效性。
