| Abstract: | This paper mainly studies the control system of position sensorless brushless DC motor based on DSP. Using the zero - crossing detection method of terminal voltage of brushless DC motor to extract the rotor position signal. Utilizing the DSP superiority of fast computing to handle the interference signal of counter electromotive force, through the introduction about pretargeting method of motor start, and thus construeting the bicyclic closed system of current control in the motor system,which can better control the hardware and software of the motor. |
