Research on Weakening Control of Asynchronous Motor with Load Based on Vector Control

Abstract

Abstract-As for the induction motor with load needs to run in a large area, so speed regulation is an essential part of the current at a higher speed to prevent the voltage and current exceeds the rated value of the normal operation of the motor damage to the need for reasonable distribution, That is, the motor into the weak magnetic area in order to achieve the motor speed. Under the rotor flux orientation control, the current closed-loop control algorithm is realized based on the traditional 1 / wr flux-weakening control, and the algorithm is implemented in MATLAB. Meanwhile, the pid Parameter tuning, the results also show the effectiveness of the algorithm.

Speed control for traction motor of urban electrified train in field weakening region based on backstepping method

“…However, field oriented control method (FOC) with optimal flux levels clearly calculated as a function of machine parameters; controlled by direct torque control (DTC) method with controllers being PI. Tang and Huang [10] designed the speed control of IM in weakening field region by regulating PID parameters.…”
