无刷直流电机控制系统设计

Design of Brushless Direct Current Motor Control System

介绍了一种无刷直流电机的控制系统,由无刷直流电机、dsPIC30F4011单片机、IM14400驱动电路等组成,实现电机转速的闭环控制。系统经过霍尔传感器位置信号采集、电机换相信号输出、转速测量等过程后,采用适当的PI算法,调节PWM信号实现电机转速闭环控制。

This paper introduces a brushtess direct current motor control system,and realize speed close loop control.The system consists of brushless direct current motor,dsPIC30F4011 microcontroller,IM14400 drive circuit,etc.System completes acquisi- tion of hall position sensor signal,output of motor commutation signals,measurement of motor＇s speed,and the digital PWM signals are adjusted to realize the close loop control of the motor with appropriate PI arithmetic.
