| Abstract: |
| Synchronization of Lorenz hyper-chaotic systems is studied.Based on the Lyapunov stability theory,a combined synchronization method of hyper-chaotic systems is presented;the sufficient conditions and range of the controller’s parameter for self-synchronization of Lorenz hyper-chaotic systems are derived and carefully proved.And the mathematic model of synchronization with different structure of Lorenz and Chen hyper-chaotic systems is given.The numerical simulations also illustrate the main theoretical results and the maneuverability of the obtaining method in this paper. |
| Key words: hyper-chaotic systems synchronization control combined synchronization control |
