Synchronization of General Complex Dynamical Networks under Discrete Coupling

张华;周进;程善

  This paper analyzes the dynamical behaviours of a kind of general complex dynamical networks under discrete coupling.A simple yet generic criterion is proposed for the synchronization.Compared with the existing literatures about this research field,a distinctive feature of this work is that the network nodes are only coupled at a sequence of discrete-time moments,and the coupling strength is allowed to be sufficient small.The main result is applied to a typical nearest neighbour coupled network composed of chaotic Duffing oscillators,and numerical simulations are carried out to verify and also visualize the theoretical results.……
