变形蔡氏电路混沌控制与同步

Chaos Controlling and Synchronization in Modified Chua's Circuit

分析了变形蔡氏电路的特性,采用追踪控制的方法,实现了变形蔡氏电路的混沌控制,并且可以实现任意的目标控制.从理论上证明了控制方案是按指数收敛的,不仅实现了2种拓扑相似异结构混沌同步,而且对于不同的系统,所设计的控制器表达式一样,数值仿真结果证明该方法是有效的.

This paper analyzes the characteristics of modified Chua＇ s circuit, uses the tracing control method to realize the chaos controlling of modified Chua＇ s circuit and the controlling of any target. It is demonstrated in theory that the control plan is exponentially convergent. Besides realizing chaos synchro- nization of two kinds of topological similar variant structures, the value simulation result has proven this method valid in that for different systems, the designed controller expressiom are the same.
