具有随机网络攻击的切换信息物理系统的事件触发控制
Event-triggered control of switched cyber-physical systems with stochastic cyber attacks
摘要
Abstract
This paper focuses on the issue of event-triggered control against stochastic cyber attacks for switched cyber-physical systems.Cyber-physical systems are described as a form of switched linear systems.In order to conserve system resources and alleviate network load,an event-triggered scheme is introduced,under which the sampled data from the sensor is transmitted to the controller via the communication network when the defined error exceeds a given threshold.And two different characteristics of stochastic cyber attacks are considered in the sensor-controller communication network.Then,under cyber attacks and the designed event-triggered controller,a switched stochastic cyber-physical system model is established.In addition,by utilizing the mode-dependent average dwell time method,the corresponding switching signal is constructed.The mean-square exponential stability is guaranteed under the designed event-triggered controller and mode-dependent average dwell time switching signal,and the controller gain is presented.Finally,an example is exploited to verify the validity of the obtained theoretical results.关键词
