基于蜂拥控制算法思想的时空混沌耦合反馈控制

The coupled feedback control of spatiotemporal chaos based on the flocking algorithms

研究了由一维非线性漂移波方程描述的时空混沌的控制问题.基于蜂拥控制算法思想,提出了一种耦合反馈控制方法.数值研究表明:不论选择真实领导者还是选择虚拟领导者为控制的目标态,只要适当选择控制强度,漂移波时空混沌都能被控制到有序的态.并且根据空间电势的关联阐述了控制机理.

Spatiotemporal chaos control in a one-dimensional nonlinear drift-wave equation is considered.We propose a method of coupled feedback to suppress the spatiotemporal chaos of the drift-wave,based on the flocking algorithms.By using real agents and virtual agents as our target,we show numerically that the spatiotemporal chaos can be controlled to a regular state if appropriate control strength is chosen.The physical mechanism is analyzed based on the correlation coefficient
