Chaos synchronization in unified chaotic systems with uncertain parameters is discussed in this paper. On the basis of the control Lyapunov function (CLF), a feedback controller is designed which is only related to the boundaries of the uncertain parameters. Synchronization of two identical unified chaotic systems with different initial conditions is realized. Simulation results for Lorenz, Lu and Chen chaotic systems are provided to verify the effectiveness of the proposed scheme. (C) 2007 Elsevier Ltd. All rights reserved.
