Design and Simulation Analysis of New Energy Vehicle Motor Drive Control System
This paper mainly explores the design scheme of the motor drive control system of new energy vehicles,and conducts simulation experiments on the motor speed.The system uses STM32 chip to process information such as the position and speed of the rotor,take the deviation between the set speed and the ac-tual speed as the input of the controller,and use the output signal to change the motor voltage,so as to re-alize the control of the motor speed and torque,and make the actual speed track the design speed in real time.From the simulation results,the error between the actual speed and the design speed is maintained within±5％,and the motor speed is stable,in line with the design expectation.
