Event-triggering H∞ synchronization for discrete time switched complex networks via the quasi-time asynchronous controller

This paper is concerned with the problem of event triggering H-infinity synchronization control for discrete -time switched complex networks via quasi-time asynchronous controllers. One event triggering mecha-nism is introduced with the triggering parameters depending on triggering states. Applying quasi-time dependent multiple Lyapunov functions and the mode-dependent average dwell time technique, quasi-time dependent synchronization conditions are obtained with a lower weighted performance index. And then, a quasi-time dependent asynchronous controller is designed with quasi-time dependent control gains in each triggering interval. In addition, not only no more than one switching, but also mul-tiple switchings are taken into account in each triggering interval, by which the assumption in some existing results is relaxed. Finally, the proposed result is applied to the PWM-driven boost converter. (c) 2020 Published by Elsevier B.V.
