Title:
VALVE CONTROL DEVICE, FLUID-PRESSURE CONTROL DEVICE, AND VALVE CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2017/090753
Kind Code:
A1
Abstract:
A valve control device according to the present invention is provided with: a correction unit that corrects the hysteresis of an output of a control valve according to the increase/decrease direction of a control output value; a detection unit that detects an actual output value for the control valve corresponding to the control output value; and a prohibition unit that prohibits correction performed by the correction unit after the increase/decrease direction of the control output value is switched until the difference between the control output value and the actual output value falls within a predetermined range. Thus, the output of a linear control valve can be brought close to a target while taking hysteresis into account.
