Autonomous hydraulic drive appears to be an autonomous hydraulic system with the variable flow pump and a servo drive with the throttle control combined in a unified system. The drive consists of a two-stage direct-acting hydraulic control valve with the electromechanical converter of the “linear electric motor” type in the first stage and with a bypass valve in the second amplification stage. Autonomous hydraulic drive operation was simulated with adaptive adjustment of the discharge pressure under the external load; it was designed to increase the drive energy efficiency. Performance of the proposed algorithm for adaptive adjustment of the autonomous power supply discharge pressure was studied in the MATLAB-Simulink simulation environment; reduction in fluid heating during throttling was assessed at various loading values and compared to the hydraulic drive without the load adaptability.
