Switching event-triggered fuzzy resilient control for networked unmanned surface vehicle under denial of service attacks

This paper studies fuzzy output feedback switching dual-channel event-triggered resilient control design problem for unmanned surface vehicle (USV) systems under denial of service (DoS) attacks. Firstly, Takagi–Sugeno (T-S) fuzzy model is applied to model USV systems, and then based on the T-S fuzzy USV systems and by using transmitted output signals, a fuzzy state observer is designed to estimate the immeasurable velocities. Secondly, to reduce communication resources of sensor to remote control station (RCS) channel and RCS to actuator channel, a switching dual-channel event-triggered mechanism is presented. Subsequently, by utilizing the designed fuzzy state observer and switching dual-channel event-triggered mechanism, a fuzzy output feedback switching event-triggered resilient control scheme is presented and the sufficient asymptotic stability conditions of the controlled T-S fuzzy USV systems under DoS attacks are established, which are formulated by matrix inequalities. Finally, the computer simulation and comparison results are developed, via MATBLAB 2024a to verify the feasibility of the presented resilient control scheme.
