CIRCUITO DI SERVOCONTROLLO DIGITALE PER CONTROLLARE UN MOTORE DI AZIONAMENTO. |
摘要 |
A digital servo control system for controlling a drive motor accumulates speed and phase error numbers and produces a pulse width modulated signal in response thereto. Phase errors are measured by counting pulses of a clock signal between the arrival of a position signal related to a rotational position of the drive motor and the arrival of a reference signal. An automatic residual error compensating circuit controls a delay applied to the position signal in accordance with residual phase error to minimize the same. |
