优化策略在不同类型混沌系统同步中的应用

摘要

A novel chaotic synchronization controller is proposed based on the optimal methed,which is used to synchronize two strictly different chaotic systems. To make this controller practicable,extended state observer (ESO)is used to compensate the system structure difference with the help of available synchronizing error. And the synchronization of different chaotic systems is completed using this controller. The numerical simulations are carried out to show the effectiveness of this method.%利用Lagrange优化策略设计同步控制器，根据扩张状态观测器(ESO)对系统之间的结构信息进行渐进估计，给出一个可实现的同步制策略，实现了两个不同结构的混沌系统之间的同步。以Duffing和Vander Pol系统为例进行仿真，效果良好。
