Switched Reluctance Motor Servo System Based on PIC16F1508

本文以PIC16F1508单片机为控制核心,利用其PWM模块、CLC模块、TMR1模块的组合进行脉宽调制和速度检测,使用开关磁阻电机专用驱动功率芯片FCAS20DN60BB作为驱动,实现对开关磁阻电动机的伺服控制。本控制系统结构简单,减少了外部逻辑器件的使用,并且提高了系统的可靠性、大大降低了系统的成本。通过使用370W、四相8/6极开关磁阻电机作为控制对象,取得了较好的实验效果。

The design takes PIC16F1508 as the control core, which uses PWM module,CLC module and TMRI module for pulse width modulation and speed detection, and it uses the switched reluctance motor drive power chip FCAS20DN60BB as a driver to realize the servo control for the switched reluctance motor. This control system has the advantages of simple structure,less usage of the external logic device, high reliability and low cost. By using the 370W, four phases 8/6 SR motor as the control object, the experiment achieves good results.
