It investigates the local and global synchronization of nonlinearly coupled complex dynamical networks.Unlike the existing synchronization methods,propose a new approach to design the synchronization controller.This method can only use the nodes' outputs of a complex network to construct synchronization controllers and it overcomes the shortcomings of the existing method which uses the nodes' state variables to design the controller.The controller proposed is much more easier to achieve.Furthermore,synchronization criteria is achieved for a complex network on the basis of the Lyapunov stability theory.Using the Lorenz system as a node of the network,studies have shown that the network can be synchronized under the proposed controller and numerical simulations are given to demonstrate the effectiveness of the proposed method.
