Synchronization for Network Chaotic Systems with Time-Delays via Intermittent Control

In order to improve the security system with high randomness and unpredictability, the synchronization problem of network chaotic system with time-delay is studied in this paper. Exponential synchronization criteria are established via intermittent control scheme. In the scheme, the outer coupling matrix is not necessarily assumed to be symmetric or irreducible. Further, for a class of networks with an irreducible and balanced outer coupling matrix, an intermittent control scheme is adopted for achieving synchronization. Numerical simulation is demonstrated to verify the effectiveness of the theoretical result.
