Control devices, control units, and pump systems

Abstract

The present invention provides a control device, a control unit, and a pump system. The control device enables easy control of an actuator driven by a hydraulic pump. The control device controls the hydraulic pump (130) of a host (100). The host (100) includes first sensors (190, 191) that detect physical quantities of the actuator (110). The control device includes: a flow control unit (212) that controls the flow rate of the actuating oil; a pressure control unit (211) that controls the pressure of the actuating oil; a first control unit (214, 216) that controls the physical quantities of the actuator (110); and a communication unit (210) that receives first information, which includes a target value of the physical quantity of the actuator (110) output from a host control unit (300) connected to the host (100) and the current value of the physical quantity output from the first sensors (190, 191). Based on the first information, the control device selects the control required for each process of the host (100).
