Abstract
A valve control device performs feedback control of a drive mechanism for a wastegate valve provided for a supercharger of an engine on the basis of a sensor signal indicating a real degree of opening of the wastegate valve and a target degree of opening of the wastegate valve, and includes a gain setting unit configured to set different control gains when the wastegate valve is closed and when the wastegate valve is opened.
