Hybrid-triggered Stabilization for Switched Cyber-physical Systems subject to Denial-of-service Attack

This work presents a hybrid-triggered stabilizing approach for switched cyber-physical systems to address the restricted transmission delay caused by denial-of-service (DoS) attack in communication environments. We initially devise a hybrid-triggered communication scheme that incorporates continuous event-triggering and periodic time-triggering conditions, selectively adopting the different conditions based on the attack’s behavior. Subsequently, we establish the relationship among the number of consecutive packet dropouts caused by DoS attack, adjustment parameters, and sampling period to develop necessary conditions for achieving the desired control performance at each controller update interval. Furthermore, the criteria are proposed to ensure the global asymptotical stability of such system through designing the average dwell time switching and sampled controllers. Finally, an example is provided to substantiate our analysis.
