摘要
提出了通过两种不同方法来讨论不同混沌系统之间的同步问题——active控制同步法和非线性控制同步法,并且各自设计了两个不同的控制器,使得响应系统和驱动系统同步.与传统的混沌同步方法相比较,提出的这两个方法不需要计算条件Lyapunov指数,因此比较简单、有效,并以Rucklidge系统和Hadley循环系统为例加以说明.通过数值模拟证实了所提出的两种方法的有效性,而且这两个控制器对于一般的混沌系统也是适用的.
Two different methods active control synchronization method and nonlinear control synchronization method are presented to study the synchronization of the different chaotic systems. Two different controllers are designed for synchronizing response system and drive system. Compared with traditional approaches, the proposed methods are much simpler and effective, because the Lyapunov exponents are not required to calculate. Rucklidge attractor system and Hadley circulation system are treated as examples. These two methods are applicable for general chaotic systems.
