The subject of the graduate qualification work is «Closed-loop reciprocating motion hydraulic drive». This work is devoted to the design of an electrohydraulic automatic control system, the output stage of which is a hydraulic drive with throttle control and constant pressure at the source, the executive element of which is a double-acting hydraulic cylinder with a double-sided rod. In this work, the method of theoretical analysis and sign modeling was used. In the course of the work, functional and schematic diagrams were built. The energy calculation of the parameters was carried out, the equipment (pump and hydraulic cylinder) was selected to provide the parameters specified in the TOR. As a result, static characteristics of the tracking system and transfer functions corresponding to the functional scheme were obtained.A dynamic calculation was performed, during which logarithmic amplitude-frequency and logarithmic phase-frequency characteristics were constructed. The original system was adjusted using sequential correction to ensure the necessary dynamic properties (accuracy and stability). The Q-factors for speed and acceleration and the maximum drive error were calculated.
