通过选取合适的控制律和控制系数,用参数自适应控制方法对响应系统某一参量调整,导致其同步,并以Logistic映象和Henon映象这两个典型的混沌系统进行数值模拟.理论分析和数值实验表明:当同步误差在一定的控制律和控制系数下渐进趋于零,同步才能实现.

This paper is concerned with the synchronization of chaotic systems. We discuss the synchronization using parametric adaptive control algorithm to adjust one of the parameters of the response system with the appropriate controlling law and controlling coefficient. To make this method realizable, the Logistic mapping and Henon mapping are taken as two typical numerical examples. Both the theoretical and numerical results seem to suggest that synchronization error will gradually be zero under the assured controlling law and controlling coefficient in which chaos synchronization will be achieved.
