Modeling and Simulation of Vector Control System for Asynchronous Motor

Abstract

Alternating current (AC) machine speed-adjusting system plays a very important role in our daily life. Firstly, this paper studies the basic principle of vector control system for three-phase asynchronous motor based on the MT coordinate system, and this paper especially gives the calculation principle diagram of the current model for rotor flux. Then this paper establishes the double closed-loop vector control system based on the Matlab/Simulink detail, and gives the simulation results. The simulation results of the double closed-loop vector control system verify the correctness of the simulation models and the principle of vector controlling.
