Event-Triggered-Based Fuzzy Control for Networked Control Systems with Compensation Mechanism Against DoS Attacks

This paper investigates the design problem of event-triggered (ET) fuzzy controller for networked control systems subject to denial-of-service (DoS) attacks via compensation scheme. Firstly, for constrained communication bandwidth, an ET scheme is introduced to save network resources. Secondly, based on the DoS attacks compensation scheme, the unfavorable impact of DoS attacks on the system is alleviated. Compared with most of the existing methods, the attack compensation mechanism introduced in this paper can maintain data transmission during DoS attacks. Combining the above content, the Lyapunov stability theory is utilized to identify the sufficient conditions for the closed-loop system to be asymptotically stable. Finally, simulation verification is presented to demonstrate the effectiveness of the proposed control strategy.
