Exponential synchronization of nonlinear coupled dynamical networks with a delayed coupling

摘要: Abstract In this paper, we discuss exponential synchronization of nonlinear coupled dynamical networks with a delayed coupling. Sufficient conditions for both delay-independent and delay-dependent global are obtained based on Lyapunov functional method. It is shown that, some chaotic systems coupling functions, if the delay less than positive threshold, then network will be synchronized. On other hand, increase delay, synchronizability restrained, even eventually de-synchronized. Finally, an example provided to demonstrate effectiveness proposed results.
