Abstract:
A valve control device configured such that a pressure measurement value of a chamber, a target pressure value of the chamber, and an opening degree measurement value of the vacuum valve are input to the valve control device and configured to control an opening degree of the vacuum valve based on a deviation between the pressure measurement value and the target pressure value, comprises: a storage storing a correlation between the opening degree of the vacuum valve and a conductance of a system including the vacuum valve; and a correction gain setting section obtaining, based on the correlation, a change rate of the conductance in association with an opening degree change at the input opening degree measurement value, thereby setting an inverse of the change rate as a correction gain. The opening degree of the vacuum valve is controlled based on the deviation and the correction gain.

Claim (Index 5):
The valve control device according to  claim 1 , wherein\n the storage stores multiple correlations for different gas flow rates, and the correction gain setting section selects, based on a gas flow rate of the system, one correlation from the multiple correlations stored in the storage, thereby setting the correction gain based on the selected correlation.
