FIELD: machine building.SUBSTANCE: throttle electrohydraulic drive with an electrohydraulic booster with mechanical feedback as to the position of a spool valve is designed for control of actuating devices of different objects, for example steers of aircrafts. An integrating link is introduced to an internal circuit of the electrohydraulic booster, which is closed with negative feedback as to the speed of an output link. Using it, transfer function of the electrohydraulic booster with mechanical feedback as to position of the spool valve is converted to the transfer function of the electrohydraulic booster with a freely floating spool valve.EFFECT: improvement and stabilisation of dynamic characteristic of the electrohydraulic drive at variation of operating conditions.1 dwg |
