Dynamic event-triggered fuzzy tracking control for networked systems with cyberattacks

This manusript focuses on the issue of dynamic event-triggered fuzzy tracking control for networked systems in the presence of denial-of-service (DoS) attacks. By using a dynamic event-triggered mechanism, a fuzzy tracking controller is presented to defense DoS attacks and actuator fault. By integrating fuzzy systems, reference model and the event-triggered tracking controller, the closed-loop system is established. Unlike the existing studies regarding DoS attacks, more sampling information is fused in the constructed piecewise Lyapunov-Krasovskii functional (LKF), which can better reflect engineering scenes. By applying Lyapunov stability theory, the closed-looped systems with and without DoS attacks are analyzed, respectively. With the aid of the relationship of two piecewise LKF, the overall closed-loop systems attain exponential stability and tracking control performance. Finally, two examples display the proposed control design, which adapts to the requirements of tracking tasks.
