This paper studies output-based resilient control of uncertain networked control systems under denial-of-service (DoS) attacks, resilient event-triggered mechanism (ETM) and quantisation. Firstly, to save constrained system resources such as network bandwidth, using information of DoS attacks and sampled outputs of plant, an output-based resilient ETM is introduced. Secondly, a switched system model is built, which characterises effects of DoS attacks, the resilient ETM, plant uncertainty and quantisation in a unified framework. Thirdly, sufficient conditions for exponential stability are obtained with less conservativeness, which establish quantitative relationships among DoS attacks, the resilient ETM, plant uncertainty, quantisation, dynamic output feedback (DOF) controller and system stability. Further, co-design conditions are presented to compute parameters of the resilient ETM and DOF controller simultaneously. Finally, example illustrates effectiveness of the proposed method.

DoS 攻击和量化下不确定 NCS 的基于输出的事件触发弹性控制

本文研究了在拒绝服务 (DoS) 攻击、弹性事件触发机制 (ETM) 和量化下对不确定网络控制系统的基于输出的弹性控制。首先，为了节省网络带宽等受限系统资源，利用DoS攻击信息和工厂采样输出，引入了基于输出的弹性ETM。其次，建立了一个交换系统模型，它在一个统一的框架中表征了 DoS 攻击、弹性 ETM、工厂不确定性和量化的影响。第三，以较少的保守性获得指数稳定性的充分条件，这在 DoS 攻击、弹性 ETM、工厂不确定性、量化、动态输出反馈 (DOF) 控制器和系统稳定性之间建立了定量关系。更多，提出了协同设计条件以同时计算弹性 ETM 和 DOF 控制器的参数。最后，实例说明了所提出方法的有效性。
