一种基于时空延迟反馈的时空混沌控制方法

A Method for Controlling Spatiotemporal Chaos Based on Feedback of Spatiotemporal Delay

研究耦合映象格子中的时空混沌控制问题。根据信号的自关联度与随机度之间的关系 ,提出了通过时空延迟反馈控制耦合单峰格子中时空混沌行为的方法 ,获得了很好的控制结果。这一控制方法不需要获取时空混沌系统中不稳定周期轨道的任何信息 ,控制参数的选择与被控的时空混沌系统的参数和方程无关。

This paper deals with the problem of controlling spatiotemporal chaos in coupled map lattices (CML). Based on the relationship between the strength of selfrelation of signal and strength of its random, a method of controlling spatiotemporal chaos in CML is proposed by feedback of spatiotemporal Delay and the better results of control is obtained. This method does not need to know any information about UPO embedded in strange STC attractor. The choice of control parameter is independent of parameter and equation of the controlled spatiotemporal system.
