摘要
连续混沌系统所产生的混沌序列具有良好的密码学特性,其实现的基本思想是异地分离的混沌系统分别能长时间地稳定同步工作,即其误差系统在脉冲作用下能够在零点稳定.通过对受脉冲作用的两个连续Chua混沌系统同步问题的研究,得到相关的稳定性定理,对已有的结果进行了推广.
The sequence generated by the analog system has great property in cryptography. The basis of this thinking is that the separated systems keeps synchronization without transmiting the synchronization signals. It is the error system of the impulsive synchronization that keeps stabilization at 0. In this paper, we study the impulsive stabilization for control and synchronization of two chua systems and get the error system asymptotically stable theorem.
