Event-based finite-time H∞ synchronization control for switched complex networks with average dwell time

This paper investigates the problem of the event-triggered finite-time nonfragile H infinity synchronization control for a class of discrete time-delayed complex networks with switched topology. To decrease the unnecessary signal transmission and save control cost, the dynamic event-triggering scheme is employed in the controller-to-actuator channel where the varying triggering threshold is governed by a dynamical equation. The main purpose of this paper is to design a nonfragile synchronization controller such that the synchronization error dynamics satisfies both the finite-time boundedness and the H infinity disturbance rejection level. By constructing appropriate Lyapunov-Krasovskii functional and using the average-dwell-time technique, the desired controller gains are acquired in terms of the solution to a set of linear matrix inequalities. Finally, a numerical simulation example is provided to demonstrate the effectiveness of the proposed synchronization controller design scheme.
