ABSTRACT:
A servo control system for the positioning of a projector comprising a dit current motor having the projector connected to the shaft of the motor, and a digital computer for providing command signals to move the projector to a programmed position at a programmed velocity within a predetermined time period. A potentiometer produced an electrical signal indicative of the actual position of the projector, and a tachometer produces an electrical signal indicative of the actual velocity of the projector. Feedback means, in turn, provides a position error signal indicative of the difference between the programmed position and the actual position of the projector, provides a velocity error signal indicative of the difference between the programmed velocity and the actual velocity of the projector, and varies, in response to the position and velocity error signals, the voltage level of the command signal such that the projector will attain the programmed position within the predetermined time period. A forward feed servo enhancer generates, in response to the command signals, a forward feed enchancement signal which when combined with the command signals will reduce the velocity error signal to approximately zero volts. This, in turn, allows the direct current motor, and thus the projector to respond to command signals at frequency rates not to exceed a predetermined frequency.
