摘　　要：针对受扰混沌系统,在参数未知的情形下利用自适应滑模控制法实现了驱动系统和响应系统的鲁棒同步.该方法几乎适用于所有的混沌系统,且无需知道系统外部干扰的上界,它由自适应控制律实现.以双涡卷系统、Lorenz系统、Rssler超混沌系统为例,说明该方法的有效性和正确性.Based on the adaptive slide mode control method,we investigated the robust synchronization for a class of chaotic systems with random perturbations.This approach can be applied to may chaotic systems;and the upper bound of random perturbations is not necessarily known in advance and it is estimated through an adaptive control process.Finally,two-scroll chaotic system,Lorenz system and hyperchaotic Rssler system are taken as examples to illustrate the effectiveness of the proposed method.
