摘　　要：讨论了驱动系统和响应系统都是相同混沌映射但其中参数不同时的同步问题 .采用参数自适应控制算法 ,当混沌映射为logistic映射时 ,得到两系统同步得一个充分条件 ,而为一般混沌映射时 ,得到两系统同步的一个必要条件 .We study the synchronization of the drive system and response system which are described by the same chaotic maps but have different parameters.We propose a parametric adaptive control algorithm and show that when the maps are logistic ones,we can draw a sufficient condition for the synchronization,and that when they are general maps,we can draw a necessary condition for the synchronization.This paper also studies the synchronization of two chaotic systems which are subjected to common noise.
