摘要： Improved automated fire control apparatus includes servomotor positioned weapon(s), range-determining radar, optical sight and controller, and a data processor. Multiple, improved feedback network organizations are provided to control the optical sighting path vis-a-vis gun mount for automated lead angle implementation under overall gunner supervision. Thus, for example, optical line of sight deflection is controlled, inter alia, by radar antenna positioning, target flight projection computations as well as manual gunner signal entry.

摘要： Load actuating servomechanism apparatus includes dynamic regeneration and a mechanically damped motor-load coupling to equalize and overcome a frequency-varying load/load drive train mechanical resonance. The drive circuitry comprises a per se conventional primary motor speed controlling rate feedback loop including a cascaded rate signal command source, summing error-signal producing node, and loop frequency response shaping filter and driver amplifier for exciting a load driving motor, and a rate tachometer signal feedback element connecting a measure of the motor output speed to a subtractive input of the summing node.To broaden the response band of the primary feedback circuit and accommodate a mechanical resonance otherwise interfering therewith, a secondary, positive feedback path supplements the input rate command with a signal dependent upon motor current, and thus upon motor load. Accordingly, output load drive automatically increases as motor current increases when a load drive retarding mechanical resonance is encountered. Further, the mechanical damping, for example implemented by a slip clutch, lowers the effective Q of the resonance, thereby facilitating load actuation.
