以空间一雏复Ginzburg—Landau振子系统为模型,研究时空混沌系统的可控性.通过对局域反馈方法的优化,提出一种新的错位反馈注入控制方法.数值实验结果表明,通过调整控制器的错位间隔,该方法可以扩展可控区域参数空间的控制强度和控制器数目范围,提高时空混沌控制的效率.
The model of 1 D complex Ginzburg-Landau oscillators was used to investigate the controllability of spatiotemporal chaotic systems. By considering local feedback injections, a new approach of shift drivings to deal with turbulence (spatiotemporal chaos) was presented . Numerical simulations show that the method can be used to expand the controllable regime of intensity and number of feedback injections by properly selecting the shift iterations of controllers.
