摘要
以复Ginzbuurg-Landau方程为模型,提出了时空混沌同步的随机巡游反馈方法,研究了利用低维信号同步偏微分方程系统中的高维时空混沌的可能性。数值实验结果说明了控制强度和巡游时间与控制效果之间的关系,并给出了可同步参数区域。在实际应用上,证明高强度控制器在巡游操作较快的情况下更容易实现时空混沌的同步。
Random itinerant feedback approach of synchronizing spatiotemporal chaos in partial differential equation system is presented. Parameter relations of synchronous region among intensity of synchronization and itinerant time are found by applying numerical simulations. It is concluded that better chaotic synchronization can be achieved by using controllers with higher intensity and faster itinerant operation in practical applications.
