用迭代最小二乘法辨识异步电动机漏抗

Estimation for Asynchronous Motor Leakage Reactance by means of the Iterative Least--squares Method

提出了迭代最小二乘寻优法辨识异步电动机漏抗的数学模型，采用ＭＡＴＬＡＢ语言编写了通用计算程序，估算鼠笼型异步电动机Ｔ型等效电路中的定、转子漏抗。该方法具有较高的计算精度、计算时间短及定、转子漏抗初值的变化对算法精度影响不大的特点。

The problem that estimation for asynchronous motor leakage reactance by means of the iterative leastsquares method is discussed, a common program is established for general use with MATLAB language, and is applied to estimate stator and rotor leakage reactance of T equivalent circuit for the induction motor with squirrelcage rotor. The calculation method has not only a fairly high accuracy, but also virtues of short calculation time and the initial value of stator and rotor leakage reactance having no effect on accuracy.
