摘要
提出了通过外部混沌信号驱动两个混沌系统的某个参量并导致其同步的方法 ,以logistic映象和Lorenz系统这两个典型混沌系统为例 ,数值地研究了这种混沌同步方法 .模拟结果表明 ,当被驱动参量的变化范围足够大时 ,两个或多个混沌系统在新的动力学的基础上达到完全同步 .特别强调指出的是 。
The method of synchronizing chaos based on driving a certain parameter of chaotic systems using the chaotic signal outside is proposed. The Logistic map and the Lorenz systems are taken as two typical examples. The simulation results show that two identical chaotic systems can be synchronized completely when the change scope of the parameter driven is large enough. On the other hand, the different synchronization states depending on the initial conditions and the controlling parameter are found in Lorenz systems.
