Event-triggered resilient control for cyber-physical systems under periodic DoS jamming attacks

This paper considers the event-triggered resilient control problem for cyber-physical systems against periodic denial-of-service (DoS) attacks. Firstly, a novel event-triggered scheme without Zeno behaviors is presented to save network resources and eliminate the occurrence of invalid events during periodic DoS attacks. Subsequently, by constructing a predictor-based event-triggered control framework, the upper bound of the prediction error related to periodic DoS attack parameters is given. Furthermore, sufficient conditions related to periodic DoS attack parameters are established to ensure the input-to-state stability. It is shown that the proposed design method can achieve better system performances than the existing ones when the system suffers the same degree of periodic DoS attacks. Finally, the theoretical research results are validated through a batch reactor system model. (c) 2021 Elsevier Inc. All rights reserved.
