摘要

本文研究了异步电动机定子和转子绕组电阻的估计问题。为此,提出了一种基于模型参考自适应系统(MRAS)的估计器。该估计器利用电机的有功功率和无功功率两个量,因此被命名为PQ-MRAS。该系统的主要优点是可以同时计算定子和转子的电阻。文中给出了该估计器的详细描述和数学模型。并给出了用MATLAB/Simulink软件对各种情况进行仿真测试的结果。

Simultaneous Estimation of the Stator and Rotor Resistances in an Induction Motor Drive using Novel Active and Reactive Power Based Model Reference Adaptive System
The paper is concerned with estimation of a stator and rotor windings resistances of an induction motor. For this purpose, a novel estimator is proposed which is based on a model reference adaptive system (MRAS). The estimator utilizes two quantities such as active and reactive power of the motor therefore is named PQ-MRAS. The main advantage of proposed system is possibility to simultaneous calculation of stator and rotor resistances. In the paper a detailed description and mathematical model of the novel estimator is provided. Results of simulation tests for various cases performed by MATLAB/Simulink software are presented as well.
