description: The purposes of this work are creating of closed-loop hydraulic drive mathematical model, plotting of logarithmic amplitude-frequency characteristics and logarithmic phase-frequency characteristics, transient process estimation, corrected system gain evaluation.
 Hydraulic circuit diagram and functional diagram were developed. Energy calculations were performed, power hydraulic drive components (actuator and pump) were selected, hydraulic control system components parameters were estimated. Closed-loop system static characteristics (for power and control hydraulic drives) were obtained. Transfer functions were obtained also according to functional diagram.
 To control power unit pump a housing with integrated hydraulic cylinder was designed. On the housing a hydraulic directional valve with designed spool is mounted.
 Logarithmic amplitude-frequency characteristics and logarithmic phase-frequency characteristics were plotted, correction method was defined, and initial system was corrected.
