ABSTRACT:
The disclosure describes a digital servo control circuit to actuate an analog servo motor smoothly from an actual present position to a new desired servo position in response to digital information from a computer. The control circuit described receives from a computer digital information representative of a new position desired at a predetermined velocity rate. Such information normally is pre-timed to correspond with a preselected timing rate in the digital computer. A position signal generator is responsive to such pre-timed digital information to generate a predetermined number of position signals intermediate of the pre-timed digital information to achieve the desired smooth operation of the servo motor.
