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.

受多重网络攻击的网络系统的动态事件触发输出反馈控制。

本文研究一类遭受多重网络攻击的事件触发网络系统的 H∞ 输出反馈控制问题。两个动态事件触发发生器分别配备在传感器和观察器端，以降低不必要的数据传输频率。传感器到观察者 (STO) 通道和观察者到控制器 (OTC) 通道分别受到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，可以保证得到的闭环系统是渐近均方稳定的（AMSS），具有规定的 H∞ 性能。而且，我们提供所需的输出反馈控制器设计方法。最后，通过实例证明了所提方法的有效性。
