Time-Varying Lag Synchronization of Complex Dynamical Networks with Unknown Channel Time-Delay

摘要

In this paper, time-varying lag synchronization is proposed. Lag time is not fixed but time-varying because the channel delay is usually time varying. Moreover, this channel delay is unknown in this paper. Suitable controller is needed to achieve the lag synchronization between two networks in which every node is a dynamical system, and channel delay between them is unknown and time-varying. Lyapunov function is key theorem to derive sufficient condition. We give one simulation example to show the theory is true and can be applied effectively.
