Simulation of switched reluctance motor control algorithm based on Simulink

Abstract

This paper analyzes the working principle of switched reluctance motor and the commonly used control algorithm in the process of motor operation; The model of switched reluctance motor speed regulation system is built-in Matlab / Simulink environment, and the effects of different control strategies on motor speed, torque and flux are simulated and analyzed; Based on the simulation analysis, the S-function is compiled to improve the traditional direct instantaneous torque control strategy and add it to the motor control model. The improved current and speed double closed-loop motor speed regulation control system based on torque control is designed and compared with the current chopper control system. The simulation results show that the improved current and speed control system is based on torque control The speed double closed-loop speed regulation system has the advantages of a fast start, small pulsation, strong load capacity, and stable operation. It is more suitable for the speed regulation control of switched reluctance motor.
