摘要
研究了一种基于ARM的开关磁阻电机控制系统。系统使用三相12/8开关磁阻电机,采用ARM微控制器LPC2214作为控制系统的核心,采集位置传感器的反馈信号,控制每相绕组的通电顺序,实现对开关磁阻电机的调速控制。对功率变换器及其驱动、位置检测、电流检测、故障保护、串口通信和液晶显示等硬件电路和软件控制策略进行设计,使整个系统结构简单,具有良好的调速性能和控制特性。
A switched reluctance motor drive(SRD) of three-phase 12/8 switched reluctance motor(SRM) based on ARM was presented.The ARM LPC2214 regulated speed of SRM by collecting feedback signals and control-ling the power-on order of each phase.Hardware circuits and software strategies of power inverter and its drive,posi-tion detection,current detection,error protection,serial interface communication,liquid crystal display(LCD) and so on were analyzed.This system had a brief structure and a good performance of speed regulation.
