PROBLEM TO BE SOLVED: To provide a valve control device for bringing the output of a linear control valve closer to a target while considering a hysteresis.SOLUTION: A valve control device comprises: a correction part for correcting the hysteresis of the output of a control valve in accordance with the increasing/decreasing direction of a control output value; a detection part for detecting an actual output value to said control valve corresponding to the control output value; and a prohibition part for prohibiting a correction by the correction part till the difference between a control output value and said actual output value falls within a predetermined range after the increasing/decreasing direction of the control output value was switched.SELECTED DRAWING: Figure 1
【課題】ヒステリシスを考慮しつつ、リニア制御弁の出力を狙いに近づける。【解決手段】弁制御装置は、制御弁の出力のヒステリシスを制御出力値の増減方向に応じて補正する補正部と、制御出力値に対応する前記制御弁への実出力値を検出する検出部と、制御出力値の増減方向を切り替えた後、制御出力値と前記実出力値との差が所定の範囲内となるまで補正部による補正を禁止する禁止部と、を備える。【選択図】図1
