| Abstract: | A digital brushless DC motor control system was designed based on TMS320LF2812A digital signal Processor(DSP).The system using the hall sensor was used to gain the rotor position.PID arithmetic was used to a-chieve the high precision,which effectively produced PWM signals to drive BLDCM with better electric current pro-tection function.The experiment result showed that the system had good dynamic and static characteristics in addition to its high credibility of the motor. |
