This article is concerned with the problem of the H output feedback control for a class of event-triggered networked systems subject to multiple cyber attacks. Two dynamic event-triggered generators are equipped at sensor and observer sides, respectively, to lower the frequency of unnecessary data transmission. The sensor-to-observer (STO) channel and observer-to-controller (OTC) channel are subject to deception attacks and Denial-of-Service (DoS) attacks, respectively. The aim of the addressed problem is to design an output feedback controller, with the consideration of the effects of dynamic event-triggered schemes (DETSs) and multiple cyber attacks. Sufficient condition is derived, which can guarantee that the resulted closed-loop system is asymptotically mean-square stable (AMSS) with a prescribed H performance. Moreover, we provide the desired output feedback controller design method. Finally, the effectiveness of the proposed method is demonstrated by an example.
本文关注一类遭受多重网络攻击的事件触发网络化系统的H输出反馈控制问题。分别在传感器和观测器端配备了两个动态事件触发生成器，以降低不必要的数据传输频率。传感器到观测器（STO）通道和观测器到控制器（OTC）通道分别遭受欺骗攻击和拒绝服务（DoS）攻击。所解决问题的目的是设计一个输出反馈控制器，同时考虑动态事件触发方案（DETS）和多重网络攻击的影响。推导了充分条件，可保证所得闭环系统在规定的H性能下渐近均方稳定（AMSS）。此外，我们提供了期望的输出反馈控制器设计方法。最后，通过一个例子验证了所提方法的有效性。
