Stability Analysis Of Switched Singular Systems Based On Event-triggered Control

Stability is an important index to measure the system performance,Lyapunov asymptotic stability and exponential stability reflect the behavior of the system ap-proaching zero in infinite time interval,finite-time stability and input-output finite-time stability can reflect the behavior of the system in a short time.In this paper,the stability of switched singular systems is studied by combining event-triggered con-trol and switching methods.This paper involves the following aspects:exponential stability of switched singular systems based on event-triggered control,and input-output finite-time stability of switched singular systems based on event-triggered control.The main contents are symmarized as follows:In the first chapter,the basic knowledge used in this paper,related concepts and research status of switched singular systems are introduced.In the second chapter,based on event-triggered control exponential stability of switched singular systems is studied.First,an output-based evert-triggered mecha-nism is proposed.Then,some conditions for exponential stability of switched singu-lar closed-loop systems are obtained by jointly designing event-triggered condition,switching laws and dynamic output feedback controller.In the third chapter,based-on evernt-triggered control input-output finite-time stability of switched singular systems is studied.By using the Lyapnnov function and average dwell time method,switching signal and event-triggered condition are taken into account to obtain some conditions for input-output finite-time stability of switched singular closed-loop systems,furthermore,the parameters of the dynamic output feedback controller are obtained.
