摘要
In this paper, the resilient control problem for cyber-physical systems in the presence of denial-of-service (DoS) attacks which are characterized by frequency and duration properties is investigated. We consider the case that information transmission between measurement and control channels may be attacked asynchronously. A novel model is established to describe the asynchronous attack signals by a recursive characterization. Based on this model, a dynamic event-triggered resilient control approach is presented with the aim of resisting the DoS attacks. The stability criterion is derived via the Lyapunov stability theory. In contrast to the existing results on the static event-triggered mechanism, the developed method is more flexible and generates fewer events. Finally, simulation results are provided to verify the effectiveness of the proposed approach.
