ESO在具有不确定性的混沌系统同步中的应用

Synchronizing Chaotic Systems With Uncertainty Based on the Extended State Observer (ESO)

根据扩张状态观测器 (ESO)的思想构造“扩张系统”，通过挖掘同步误差中所隐含的系统信息，对扩张系统的各个状态进行估计，在此基础上设计物理上可实现的控制器，实现了两个具有模型或参数失配的混沌系统的同步。以 Lorenz系统和 Duffing,Vander Pol系统为例进行仿真，同步效果很好。

An extended system is formed based on the extended state observer (ESO), and the states of this system are estimated by collegting the information wrapped in observable synchronizing error. Then a practicable controller is provided using these estimated states to synchronizing systems with uncertainties such as structure difference or parameter mismatching. The numerical simulations are proposed to show the effectiveness of this method.
