英文摘要：

The digital control system of switched reluctance motors with fully-pitched windings and segmental rotors based on TMS320C2812 was designed in this paper. The angle position control strategy in which the turn-on angle was regulated by digital PI algorithm and turn-off angles was optimized according to speeds was adopted to realize closed-loop speed control. Each circuit unit was described and programming idea of main program and related subprogram were intro- duced in detail. Finally,the validity of the digital control system of switched reluctance motors with fully-pitched windings and segmental rotors was tested by experiments.
