基于极坐标的异步电机新型参数辨识方法
New method of parameter identification of asynchronous motor based on polar coordinates
摘要
Abstract
The accuracy of motor parameters seriously affect the control quality of the system in vector control system for asynchronous motor.This paper introduces a new identification method of the asynchronous motor parameters by using polar coordinates.The voltage,current,frequency and phase angle can be realized by software.Based on SVPWM algorithm,we impose some form of voltage singles to the asynchronous motor,and use polar coordinates method to simplify the calculation.Asynchronous motor parameters include the stator resistance,rotor resistance,stator leakage inductance,rotor leakage inductance and mutual inductance,these parameters are determined by the DC chopping test,the single-phase alternating current test and no-load test.The experimental results indicate that this method can obtain high accuracy parameters.The identification method is simple,easy to realize and will be widely used in future.关键词
