ABSTRACT:
This disclosure describes digital control circuit to actuate an analog servo motor in response to digital information from a computer. The control circuit is responsive to the timing signal (13) from the computer, and includes a circuit (12) to receive information from the computer indicative of a new servo position. A feedback circuit (15) receives information from the servo indicative of the actual present servo position. Information processed individually by each of these circuits then is connected into a computational network (14) in order to generate a properly timed digital output signal which, when converted in a suitable digital-to-analog converter (17), is able to drive a servo motor accurately.
