Abstract

To realize the precise control of the brushless DC servo motor(BLDCSM),proposed a digital control sysrem of BLDCSM with three-closed-loop using TMS320F2812 Digital Signal Processor(DSP) of TI.The method of hardware electric circuit design,realization means and software programming were presented in detail.The practice shows that the control system has simple structure,low cost and good control function,such as the motor runs stably with accurate location,small torque fluctuation and agile control of speed.
