Abstract
Synchronization of N different coupled chaotic systems with ring and chain connections is investigated. The New system, the Chen system, the Lü system, the Lorenz system, and the Rössler system are used as examples in verifying effectiveness of the method. Based on the Lyapunov stability theory, the form of the controller is designed and the area of the coupling coefficients is determined. Simulations indicate that global synchronization of the N different chaotic systems can be realized by choosing appropriate coupling coefficients by using the controller.
