摘要
变量反馈技术实现了耦合双稳映象格子模型的时空混沌控制.数值实验结果表明,利用不同的反馈技术和不同的反馈强度,可以将双稳映象系统的混沌及耦合双稳映象格子模型的时空混沌控制到不动点或周期轨道.变量反馈控制法除了局域双稳映象系统的定态点外,不需要先获取耦合双稳映象格子时空系统的动力学信息,它对抑制耦合双稳映象系统中的湍流具有一定的指导作用.
The suppression of spatiotemporal chaos is realized by using variable feedback techniques in coupled bistable map lattice systems. Numerical simulations indicate that the chaos in a bistable map system and the spatiotemporal chaos in a coupled bistable map lattice system could be suppressed to the fixed point or the periodic orbits by using different feedback techniques and strengths. In addition to the fixed point of a local bistable map system the feedback control method does not require a priori dynamics information of the coupled bistable map lattice system. The method appears useful in controlling turbulence of coupled bistable map lattice systems.
