Synchronization Control for an Uncertain Dynamical Network

Abstract:

Synchronization of an uncertain dynamical network time-delay is investigated by means of robust control schemes. This paper is devoted to the robustness analysis of controlled complex network concerning the effect of communication delay and uncertainty, where the topology is not exactly known in the synchronized process. First, we analyze the synchronization error dynamical model of the uncertain networks concerning time-delay. Then, based on this system, we derive a sufficient condition for globally asymptotical synchronization of the controlled uncertain network without time-delay in terms of linear matrix inequality by using Lyapunov approach. Furthermore, we investigate robustness property of the controlled uncertain network affected by time-delay, and give a design criterion for the control to guarantee globally asymptotical synchronization. Finally, A simulation is provided to show effectiveness of our strategies.
