以一维复Ginzburg—Landau方程(CGLE)为模型,提出时空混沌控制的一类广义反馈方法,研究利用二次函数作为反馈控制信号控制偏微分方程系统中时空混沌的可能性,利用数值模拟实验建立了控制参数与可控性所满足的关系,采用一种理论上的近似方法解释了可控参数区的对称性.
The usual linear variable feedback control method is extended to a generalized function feedback approach in the study of controlling spatiotemporal chaos in the one-dimensional ( 1 D) complex Ginzburg-Landau equation. The controllability of relevant factors is investigated by numerical simulations. An analytical theory is proposed to explain the experimental results qualitatively.
