摘要
针对Chen系统复杂的拓扑机构而难控制和同步的特点,在混沌保密通信的仿真研究中,该文首次提出用状态观测器方法对其进行同步。该方法不需要计算同步的条件Lyapunov指数,也不需要同步的两个混沌系统的初始状态处于同一吸引域,因而操作起来非常方便。仿真结果表明,无论是对受到干扰大或小的Chen系统,其同步效果都是非常卓越的。另外,该文还对仿真结果中的一些有趣现象进行了分析论证。
More and more attentions have been pl ac ed on the Chen's in the area o f secure communication based on the chaos because of its good properties.But we can't obtain good effects when using the mothords discovered before in contro lling and synchronizing it.In this paper,we propose a methord based on the state-observor.The experimental results show that the methord is very efficient and pleasing.Moreover,a very interesting and useful result will be discussed in this paper.
