Adaptive Pinning Synchronization for Complex Network Coupled with the Outputs

An adaptive pinning control method is proposed for synchronization of a complex network coupled with output.Unlike existing synchrnization methods,output of a complex network is used to construct synchronization controllers,and the synchronization-controller gains are adapted according to synchronization errors,and only part of nodes need to be controlled in the complex network.Furthermore,synchronization criteria are achieved for a complex network on the basis of the Lyapunov stability theory.Numerical simulations are carried out for a small-world network and a scale-free network,the results showing effectiveness of the proposed scheme for synchronization of complex network.
