摘要
研究了一个新的三维混沌系统的全局指数吸引集及同步问题。首先基于全局指数吸引集的概念和Lyapunov函数稳定性理论,给出了全局指数吸引集的一个充分条件;然后利用所估计的界设计有效的控制器实现混沌系统的同步;最后数值仿真结果表明该方法是快速有效的。
The globally exponentially attractive set and synchronization problem of the three-dimen- sional chaotic system were researched. Firstly, based on the definition of globally exponentially attractive set and Lyapunov stability theory, a sufficient condition for the globally exponentially attractive was given. Secondly, linear feedback control was used to realize the synchronization of two chaotic systems. Finally, numerical simulations were presented to show the effectiveness of the proposed chaos synchronization scheme.
