摘要
基于Lyapunov稳定性理论,提出了一种超混沌系统混合同步控制方法,给出并详细证明了Rossler超混沌系统实现自同步的充分条件以及控制律参数的取值范围,并构建了两个不同结构的Rossler超混沌系统的异结构快速同步的数学模型。数值仿真表明了所设控制器的有效性和方法的可操作性.
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 Rossler hyper- chaotic systems are derived and carefully proved. And the mathematic model of synchronization with diverse structures of Rossler hyper-chaotic systems is given. The numerical simulations also illustrate the effevtiveness of main theoretical results and the maneuverability of the obtaining method in this paper.
