ABSTRACT:
A combined feedback control system for a servo actuator including a ram that produces a mechanical displacement output of the system as directed by a position command signal. In the combined feedback control system a lever arrangement mechanically combines displacement and velocity information of the ram, and such combined information is conveniently transduced and electrically combined with the position command signal to develop an error signal that controls an electro-hydraulic valve. The latter preferably through a fluid amplification stage controls the delivery of fluid to the ram and, thus, the position thereof. Through the lever arrangement a mechanical failure control is operative to move the ram to a predetermined position upon failure of the electro-hydraulic valve and a manual control is operable to control the ram position via the fluid amplification stage.
