This paper studies output-based decentralised event-triggered dissipative control of NCSs under aperiodic DoS attacks. Firstly, to save constrained system resources such as network bandwidth, using information on aperiodic DoS attacks, an output-based decentralised resilient event-triggered mechanism (ETM) is introduced. Secondly, a switched system model is built, which characterises effects of aperiodic DoS attacks, decentralised resilient ETM and disturbances in a unified framework. Thirdly, sufficient conditions are derived such that the system is exponentially stable and strictly $(\mathcal{G}$, $\mathcal{H}$, $\mathcal{I})$-dissipative, which establish quantitative relationships among aperiodic DoS attacks, decentralised resilient ETM, disturbances and system performance. Further, co-design conditions are presented to compute parameters of switched dynamic output feedback controller and decentralised resilient ETM simultaneously. Finally, examples illustrate effectiveness of the proposed method.

本文研究了非周期性 DoS 攻击下 NCS 的基于输出的分散事件触发耗散控制。首先，为了节省网络带宽等受限系统资源，利用非周期性DoS攻击信息，引入了基于输出的分散弹性事件触发机制（ETM）。其次，建立了一个交换系统模型，在一个统一的框架中表征非周期性 DoS 攻击、去中心化弹性 ETM 和干扰的影响。第三，推导出充分条件使得系统指数稳定且严格$(\mathcal{G}$, $\mathcal{H}$, $\mathcal{一世})$-耗散性，在非周期性 DoS 攻击、分散的弹性 ETM、干扰和系统性能之间建立定量关系。此外，还提出了协同设计条件，以同时计算开关动态输出反馈控制器和分散式弹性 ETM 的参数。最后，实例说明了所提出方法的有效性。
