Abstract: Discussed the adjusting speed system in brushless DC motor from the view of two points of the driving mode and the close-loop algorithm.The SVPWM technic was realized by dsPIC30F6010,and used the speed close-loop PID algorithm with gear-shift integral,banished the integral saturation problem,made motor adjusting speed process rapid and smooth.The experiment result show that the control and algorithm are correctness.
