Stabilization of nonlinear systems using event-triggered controllers with dwell times

In this paper, the problem of event-triggered stabilization is investigated for a class of nonlinear systems. By adding different dwell times to static and dynamic event-triggering mechanisms, respectively, two event-triggered control strategies are proposed to ensure that the closed-loop system under study is asymptotically stable with the Zeno phenomenon being excluded. Barbalat's Lemma and sufficient Lyapunov stability conditions are used to compute different dwell times. Comparative study is made and illustrated for the static and dynamic event-triggering mechanisms by a numerical example.
