Abstract: Based on TMS320F2812DSP(Digital Signal Processor), direct digital control system of hardware and software for switched reluctance motor(SRM) was designed. Hardware system includes power inverter, the drive of IGBT, position signal capture, etc. Software system includes the setting of switching-on and off angles, speed adjusting, etc. Experiment result validates the feasibility of these designs.
