Abstract
This article is concerned with the problem of event-triggered dynamic output feedback control for switched cyber-physical systems subject to stochastic cyber attacks. Two kinds of stochastic cyber attacks obeyed the Bernoulli distribution are taken into account, and a switched stochastic system is derived. An event-triggered strategy is adopted to reduce unnecessary communication and save system resources, and then an event-triggered–based dynamic output feedback controller is designed. The sufficient conditions for the mean-square exponential stability of the switched stochastic system are given by taking advantage of the mode-dependent average dwell time method and the multiple Lyapunov functional technique. Finally, the validity of the proposed theoretical results is verified by two examples.
