This work is devoted to the static and dynamic calculation of a hydraulic drive as part of an electrohydraulic automatic control system. The purpose of the work is to calculate the basic parameters of a tracking hydraulic drive with hydraulic cylinders. In the future, in the final qualifying work, the nominal pressure of the hydraulic drive was selected, a basic hydraulic circuit was drawn up, the geometric parameters of the hydraulic cylinders were calculated. The main geometric parameters of the throttling hydraulic distributor are also determined: the maximum displacement of the plunger and its diameter. At the same time, the parameters of the "nozzle-flap" type hydraulic booster were determined: the diameter of the nozzle and the distance between the nozzle and the flap. Then a mathematical model of the drive was compiled and the transfer functions of the hydraulic booster and the electromechanical converter were calculated. After that, the correction was carried out and the transfer function of the correction device was obtained.
