摘要: 讨论了一维复数金兹堡-朗道方程的混沌控制问题, 利用负反馈方法有效地将混沌状态控制到稳定的平面波解上.讨论了相邻控制点的距离和反馈强度在控制中的作用.在复数金兹堡-朗道方程中增加了偏流项, 随着偏流强度增加, 所需反馈控制密度减小.

关键词: 混沌, 复数金兹堡-朗道方程, 负反馈

Abstract: Controlling chaos in the complex Ginzburg-Landau equation(CGLE) is studied and chaos is controllable to the stable plane waves by negative feedback. It is found that the distance between two adjacent controlling points and feedback intensity is effective in controlling. When the CGLE is included gradient force, controlling local numbers are smaller as gradient force is larger.

Key words: chaos, complex Ginzburg-Landau equation, negativefeedback
