以一维复数Ginzburg-Landau方程系统为模型,研究时空混沌系统的可控性.基于蜂拥控制算法思想,提出了一种反馈控制方法.数值模拟结果表明,无论是选择空间均匀周期解,还是选择行波解为控制目标态,只要选择合适的控制强度,被研究的时空混沌系统都能被控制到有序的状态.最后,利用空间的关联函数解析其控制机制.
Spatiotemporal chaos control in one-dimensional complex Ginzburg-Landau equation was described.We proposed a method of coupled feedback based on the flocking algorithms.By using the homogeneous-periodic solutions and the traveling wave solutions as our target,we showed numerically that the spatiotemporal chaos can be controlled to a regular state if appropriate control strength was chosen.The physical mechanism was analyzed based on the correlation function.
