Dynamic Output Feedback Control for Networked Systems with Event-Triggered Communication and Deception Attacks

This paper investigates the problem of H∞ dynamic output feedback control for networked systems under both eventtriggered communication and malicious deception attacks. To reduce the communication burden, an event-triggered mechanism (ETM) is employed, where the transmission of sampled data is determined by a pre-defined threshold condition. Considering the practical network environment, the impact of time-varying network delays is incorporated into the system modeling. Furthermore, a deception attack model is introduced, where an adversary injects false data into the communication channel. By constructing a suitable Lyapunov-Krasovskii functional (LKF), a sufficient condition in the form of linear matrix inequalities (LMIs) is derived to ensure the stability of the closed-loop system with a prescribed H∞ performance level. Through the variable substitution technique, a co-design method for both the controller gains and the event-triggered parameters is provided. Finally, numerical simulations are presented to demonstrate the effectiveness and resilience of the proposed control strategy.
