Abstract
A valve control device controls an opening degree of a valve provided in an intake passage, an exhaust passage, or a passage connected one of these and includes an observed value acquisition unit, an inlet temperature acquisition unit, a target calculation unit, an equilibrium opening degree calculation unit, an observer, a correction opening degree calculation unit, an instruction opening degree calculation unit, and an output unit. The target calculation unit calculates an equilibrium state value and a target property value. The correction opening degree calculation unit calculates a correction opening degree by multiplying a gain matrix by a deviation vector including, a deviation between the equilibrium state value and the estimated state value and an integrated value of a deviation between the target property value and the estimated property value.
