对两个单向耦合映象格子系统提出逐点反馈的同步方法, 有效地实现了两个系统取相同参数, 不同初始条件时的同步. 通过数据模拟实验发现, 调整反馈控制参数, 可以改变同步速度. 最后, 将该方法分别推广至双向对称耦合系统, 并讨论了反馈项的选取及适合的参数范围.-The two one-way coupled map lattice system point by point feedback synchronization method to effectively realize the two systems take the same parameters, different initial conditions at the time of synchronization. Through data simulation experiment found that feedback to adjust the control parameters can be changed synchronous speed. Finally, the methods were extended to two-way symmetric coupled system, and discussed the feedback of the selected and appropriate parameters.
