【 摘 要 】

This paper studies the output regulation problem for a class of switched linear systems via designing an event-triggered state feedback controller. Compared with the time-triggered mechanism, event-triggered mechanism effectively reduces execution times of a control task. The designing of the controller for switched systems is difficult due to the mixture of event-triggered instants and switching instants. This paper gets sufficient conditions for the output regulation problem to be solvable by giving a co-design scheme of an event-triggered mechanism, state feedback controllers and switching rules satisfying the average dwell time (ADT) condition. The different coordinate transformations break the restrictions of a common solution for regulator equations of all subsystems. Moreover, the minimum inter-event interval is given to avoid Zeno behavior. Finally, a simulation example of the switched RLC circuit systems shows the validity of the results.
