Abstract: The input-output finite-time stability of asynchronous switched system due to the switching delays of controllers with uncertainties under event-triggered sampling scheme is investigated. Firstly, the concept of input-output finite-time stability of system is given, and a state feedback controller is designed based on event-triggered sampling scheme. Secondly, some sufficient conditions for input-output finite-time stability of uncertain asynchronous switched closed-loop systems are derived by applying multiple Lyapunov functions method and average dwell time approach. Finally, a numerical simulation example is given to illustrate the validity of the conclusions.

Key words: asynchronous switching, event-triggered control, uncertain system, input-output finite-time stability
