无刷直流电机控制系统的仿真

Simulation of Brushless Direct Current Motor Control System

在Matlab/Simulink环境下,基于无刷直流电机的驱动原理,构建其控制系统模型并进行仿真分析。根据电机转子的位置信号,利用PWM调制方法对无刷直流电机的定子各相绕组电压进行控制,从而达到控制电机转速并获得性能较好的转速曲线。

In Matlab/Simulink,the simulation module of brushless direct current motor control system is established based on the principles of brushless DC motor drive.The PWM modulation method is used to control the voltage of each phase according to the different signals of the rotor position,so as to control the speed of the brushless DC motor and get better performance.
