摘要

模型参考自适应系统(MRAS)是一种简单的异步电动机速度估计方法。这是一种有吸引力的分析方案，特别是在系统参数知识贫乏的情况下。该技术结合了一个误差信号，分别通过比较参考模型(RM)和可调模型(AM)的输出来产生。产生的误差信号驱动一种适应速度计算的机制(ADM)。本文试图比较两种基于MRAS原理的矢量控制(VC)模式下IM转子转速的确定方法。比较了两种MRAS策略在不同运行模式下的速度估计和动态。在MATLAB环境下，利用Sim Power System (SPS)和Simulink工具箱在离散时间框架下进行了分析。

Model Reference Adaptive System using Rotor Flux and Back Emf techniques for speed estimation of an Induction Motor operated in Vector Control mode: A comparative study

Model Reference Adaptive System (MRAS) is a simple approach for speed estimation of an Induction Motor (IM). It is an attractive scheme for analysis especially when knowledge relating to system parameters are poor. The technique incorporates an error signal to be generated by comparing the output of the reference model (RM) and the adjustable model (AM), respectively. The error signal generated drives an adaptation mechanism (ADM) towards computation of speed. In this paper, an attempt has been made to compare two different methods based on the principle of MRAS for determination of rotor speed of IM operated in Vector Control (VC) mode. Speed estimated and the dynamics under various modes of operation in both MRAS strategies are compared. Analysis has been carried out in MATLAB environment using Sim Power System (SPS) and Simulink toolboxes in discrete time frame.
