Modeling and Simulation of Asynchronous Motor in Coordinate System Based on Matlab

Asynchronous motor has simple structure, low cost, comparable to DC motor control performance when using the vector control technology. This paper focuses on the three-phase asynchronous motor which account for most of the proportion of the AC machines. Firstly, this paper builds the vector control system of asynchronous motor, then deduces the mathematical models of asynchronous motor based onαβ coordinate system. At last the paper builds the simulation model of asynchronous motor based on αβ coordinate system in Matlab/Simulink, and the paper gives and analyzes the simulation results. The simulation results verify the correctness of the theory of asynchronous motor based onαβ coordinate system. Keywordsasynchronous motor; mathematical model;αβ coordinate system;simulation;
