Abstract

Networked switched quasi-linear parameter varying (LPV) systems can effectively describe the parameter degradation or perturbation of actual systems. For a quasi-LPV networked control system, it may be threatened by various attacks, and the communication barriers caused by attacks, delays, and triggers further make the scheduling between the controller and the system asynchronous. In this article, the event-triggered control for switched quasi-LPV system subject to denial-of-service attacks and scheduling asynchronization is concerned. Two event-triggering mechanisms are utilized to reasonably adjust the communication frequency of state and scheduling variables, which can reduce their transmission risk of being attacked. Under the influence of periodic and aperiodic DoS attacks, complete event-triggered control schemes for networked switched quasi-LPV system are given. Especially, a set of sufficient conditions for analysis and synthesis is presented, which solves the tricky problem of scheduling asynchronization. Finally, a numerical simulation and a switched <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">RLC</i> system example are given to verify the effectiveness of the proposed method.
