THROTTLING ELECTROHYDRAULIC DRIVE

摘要

FIELD: instrument making. ^ SUBSTANCE: proposed electrohydraulic drive is designed to control actuating mechanisms of various entities, for examples flight vehicle control surfaces. The electrohydraulic actuator inner circuit uses output signal of differentiating device as a negative feedback signal. Note that the said differentiating signal input is connected to the output of output link position pickup. ^ EFFECT: simpler design and higher stability in varying operating conditions. ^ 1 dwg
