Elwakil混沌系统的混沌控制与同步

Chaotic Control and Synchronization of the Elwakil's Chaotic System

根据Hurwitz稳定性判据,提出了Elwakil混沌系统的一种控制方案,实现了Elwakil系统对任意给定的光滑参考信号的追踪,并且实现了该混沌系统的自同步以及与Rssler混沌系统的异结构同步.该方法中采用的控制器只需要知道受控系统的部分状态变量的信息,因此形式简单,容易实现.Matlab的数值仿真表明该方法的有效性.

Based on the Hurwitz stability criterion, this paper presents a control strategy of the Elwakil＇s chaotic system. This strategy can not only track any desired smooth reference signals but also realize the self synchronization and the synchronization with RtJssler＇s chaotic system. The controller of the strategy only needs partial state variables,so its form is simple and it can be realized easily. In the end, Numerical simulations at matlab are given to illustrate the effectiveness of the proposed method.
