Title: (EN) VALVE CONTROL DEVICE, LIQUID PRESSURE CONTROL DEVICE, AND VALVE CONTROL METHOD
Abstract: front page image
(EN)

A valve control device includes a correction unit that corrects hysteresis in output of a control valve according to an increasing/reducing direction of a control output value; a detection unit configured to detect an actual output value to the control valve corresponding to the control output value; and a forbidding unit configured to forbid correction by the correction unit, until a difference between the control output value and the actual output value becomes within a predetermined range, after the increasing/reducing direction of the control output value is switched.
