以常见的二阶系统为基础，对自抗扰控制器设计中的核心部分扩张观测器进行了数值仿真。仿真分为两步进行：观测器参数分别选择线性参数和非线性参数，比较这两种观测方式的效率；在观测器中引入高斯加性白噪声，检验观测器的观测效果。仿真结果表明，只要合适选择观测器的参数，就能够以较高的效率获得较为满意的观测效果。
以常見的二階繫統為基礎，對自抗擾控製器設計中的覈心部分擴張觀測器進行瞭數值倣真。倣真分為兩步進行：觀測器參數分彆選擇線性參數和非線性參數，比較這兩種觀測方式的效率；在觀測器中引入高斯加性白譟聲，檢驗觀測器的觀測效果。倣真結果錶明，隻要閤適選擇觀測器的參數，就能夠以較高的效率穫得較為滿意的觀測效果。

Numerical simulation of the extended state observer,which is the essential part of active disturbance rejection controller,was performed based on the most popular 2?order system. The simulation consists of two steps:in the 1st part,linear parameters and non?linear parameters are selected for the parameters of the observer,and compared for their observing effect;in the 2nd part,Gauss additive white noise is imported in the observer to check its observing effect. The simulation result shows that the satisfied observing effect can be obtained effectively if only its parameters are selected well.
