Research on asynchronous motor control of electric vehicle

Abstract

This article mainly aims at the electrical machinery control system, and carries on the design.of the electrical machinery control system. The motor control system is designed that adopt dual closed-loop control system for the inner current loop, outer loop for speed. In this paper, AC induction motor is chosen as the research object, and the mathematical model of AC induction motor is established, including voltage equation, flux equation, torque equation and motion equation. The simulation model of AC induction motor is established in Matlab / Simulink, the simulation results are analyzed and the correctness of motor control system is verified.
