Motor speed and position control |
摘要 |
A method of controlling the speed and position of a motor includes receiving a pulse train indicative of the speed of the motor, and a periodic signal at a frequency greater than the pulse train. The number of cycles of the periodic signal per cycle of the pulse train is counted, and compared to a predetermined number. The speed of the motor is adjusted to match the count to the predetermined number, thus effecting speed control. A command position signal defining a plurality of sampling points is generated. The number of cycles of the periodic signal between a sampling point of the command position signal and an operative edge of the pulse train is counted and compared to a predetermined number. The speed of the motor is further adjusted to match the count to the predetermined number, thus effecting position control.
