Control circuitry outputs a pump command current corresponding to an actuator operation signal to pump equipment including at least one pump whose displacement increases in accordance with increase in the pump command current. The control circuitry: stores calibration data generated based on actual measurement data of the at least one pump, the actual measurement data indicating an actual relationship between the pump command current and the displacement of the at least one pump, the calibration data being data to correct the pump command current such that the displacement of the at least one pump transitions on a performance line that is preset for the actuator operation signal. The control circuitry: determines the pump command current based on the actuator operation signal; and corrects the determined pump command current by using the calibration data, and outputs the corrected pump command current to the pump equipment.
Control circuitry for outputting a pump command current corresponding to an actuator operation signal to pump equipment including at least one pump whose displacement increases in accordance with increase in the pump command current, the displacement of the at least one pump being a delivery amount per rotation of the at least one pump,
