The article provides a brief overview of literary sources from the PRC on the study of a hydraulic drive with two-line control. This hydraulic drive is a new electro-hydraulic system for regulating the flow of a positive displacement pump, developed on the basis of control systems for the electric motor and the volumetric displacement of an adjustable positive displacement pump. The hydraulic drive has two lines of control variables: the rotational speed of the drive motor shaft and the adjustable displacement of the pump. The composite function of the two control lines allows you to create a hydraulic actuator with high efficiency and operating speed. An advanced hydraulic drive with two-line control increases the overall natural frequency of the entire system.
