一种耦合映象格子中时空混沌的级联控制法

A METHOD OF CASCADE CONTROL SPATIOTEMPORAL CHAOS IN COUPLED MAP LATTICE

提出了一种级联控制耦合映象格子 (CML)中时空混沌的方法 以耦合单峰格子为例验证了这种控制方法 ,结果表明 :在不同的系统模式和不同的控制参数下可以得到各种稳定的时空周期轨道 这一控制方法的优点是不需要获取时空混沌系统中不稳定周期轨道的任何信息 。

In this paper,a method of cascaded control is proposed to control spatiotemporal chaos in coupled map lattice(CML). The coupled logistic lattice is taken as a typical example to demonstrate the method. A series of stablized spatiotemporal periodic orbits are obtained at different system patterns and different control parameters. The advantage of this method is that it does not need to know any information about the UPOs embeded in spatiotemporal chaotic system.Choices of control parameters are independent of the variables andparameters of the contorlled spatiotemporal chaotic system.
