单向耦合映象格子系统的时空混沌同步

Synchronization of Spatiotemporal Chaos in One-way Coupled Map Lattices

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 .

A new method is proposed to synchronize two one way coupled map lattices with time dependent feedback signals through every site connections.The numerical simulation is given.It is shown that this method can synchronize two open flow systems successfully.We also find that the Speed of the synchronization depends the feedback control parameter.And finally the application of this method in symmetrically coupled map lattices and asymmetrically coupled map lattices is discussed.
