Pinning control of unstable equilibrium points for a class of chaotic complex dynamical networks

This paper addresses the control issue of unstable equilibrium points of chaotic complex dynamical networks. By using the output control method, we propose a pinning control method to control the unstable equilibrium points of the networks, which can control all the nodes of the network to their equilibrium points. The criteria for choosing control parameters are obtained based on Lyapunov stability. Taking the Chua´s circuit as a node, some simulations are given to demonstrate the effectiveness of the proposed method and criteria.
