A New Active Synchronization Method Control Parametrically Excited Chaotic Systems
摘要/Abstract
基于Lyapunov稳定性理论,提出了一种针对非自治混沌系统的新的主动同步方法,在理论推导和工程实现上有着明显的优势,不仅主动同步控制器的系统设计过程简单,推证简捷,而且适用于单频或多频参数的一大类参数激励混沌系统.通过对非线性陀螺系统与Mathieu方程2个耦合的四维非自治系统之间的同步数值仿真,证实方法的有效性.新的主动同步法不仅适合低维的混沌系统,同样适用高维的混沌系统.
Based on Lyapunov stability theory,a novel active synchronization method is proposed for a classof paramet rically excited chaotic systems. The method is predominant in theoretical deduction and engineeringrealization,the systemic designing of cont roller is simple,and can be applied to synchronize a class of paramet rically excited chaotic systems.The active synchronizations of the nonlinear gyros system and the Mathieu function,and two coupling four2dimensional non-autonomous systems are achieved by the proposed method.It is effective and robust not only for the lower2dimensional paramet rically excited chaotic systems,but higher dimensional ones.
