METHOD AND DEVICE FOR CONTROLLING BRUSHLESS DC MOTOR |
摘要 |
A system for controlling the speed of a brushless DC motor includes a microprocessor for generating stator control drive signals responsive to Hall sensors detecting relative rotor-pole-stator positions. Hall sensor signal transistions are compared against a reference frequency to provide an error signal which is processed by the microprocessor in accordance with a transfer function to emulate a type II servo loop. Stator commutation control signals are reduced in duration proportional to the resulting processed error signal. The control signals are thereafter applied to integrating current drives energizing the stator coils with triangular current signals. |
