Dynamic Event-Triggered Output Feedback Control for Networked Systems Subject to Multiple Cyber Attacks

This article is concerned with the problem of the $H_{infinity}$ 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 $H_{infinity}$ performance. Moreover, we provide the desired output feedback controller design method. Finally, the effectiveness of the proposed method is demonstrated by an example.

This article addresses the problem of $H_{infinity}$ output feedback control for event-triggered networked systems subject to multiple cyber attacks, considering dynamic event-triggered schemes and the effects of the attacks. A sufficient condition is derived to guarantee asymptotic mean-square stability and a prescribed $H_{infinity}$ performance of the closed-loop system. The effectiveness of the proposed method is illustrated through an example.
