【Abstract】 A digital control governing system of Brushless DC motor with 8031 was designed in this paper. Adopting bipolar PWM control made the motor running in four puadrants. Employing proportion plus partitoning intergration technique adjusted running speed and then decreased its overshoot and transient apparently. So dynamic performance of the system became better obviously.更多还原
