Title:
CONTROLLER AND CALIBRATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/171029
Kind Code:
A1
Abstract:
A controller (3) according to an embodiment outputs a pump command current corresponding to an actuator operation signal to a pump device that includes at least one pump of which the ejection capacity increases as the pump command current increases. The controller (3) stores calibration data for correcting the pump command current for the at least one pump so that the ejection capacity of the pump transitions on a performance line that is set in advance with respect to the actuator operation signal, the calibration data having been generated on the basis of actual measurement data that shows an actual relationship between the pump command current and the ejection capacity. The controller (3) determines a pump command current on the basis of the actuator operation signal, corrects the determined pump command current using the calibration data, and outputs the corrected pump command current to the pump device.
