Event-triggered Control For Two Classes Of Networked Switched Linear Systems Under Asynchronous Switching

The event-triggered control of networked linear switched systems is studied in this paper.Since only the activity mode and state of the sampled data can be obtained under the event-triggered mechanism,the mode of the subsystem will be mismatched with the mode of the candidate controller in a large probability,which is asynchronous switching will occur.Thus,this paper mainly discusses the event-triggered control of the frequently asynchronous switched systems and the event-triggered fault-tolerant control of the networked linear switched systems with asynchronous switching.The systems can be switched frequently during the holding interval by not limiting the minimum dwell time of each subsystems,and the stability criterion of the closed-loop systems is proposed by using the Lyapunov function related to the controller mode.However,once the systems switched during the holding interval,the controller mode will be inconsistent with the system mode,and the closed loop systems will become unstable.To ensure that a sample can be triggered within the system switched interval,then,by using a new event-triggered transmission mechanism,based on the Lyapunov control theory and the augmented switching signal technique,the fault-tolerant control problem of networked switched linear systems is studied under a given actuator fault model,and the sufficient conditions of exponential stability related to dwell time and average dwell time are given.Finally,the validity and rationality of the calculation results are verified by a simulation example.
