The present application relates to a control device for a wet flue-gas desulfurization apparatus that performs desulfurization by bringing exhaust gas generated by a combustion apparatus and absorbent liquid in an absorption tower into gas-liquid contact. The control device comprises a trained model construction unit, a prediction value correction unit, a table creation unit, and a control target value determination unit. The trained model construction unit constructs a trained model by machine learning with respect to a relationship between an explanatory variable including at least the load of the combustion apparatus, and an objective variable that is a future concentration of sulfur dioxide at the outlet of the absorption tower. The prediction value correction unit corrects the prediction value produced by the trained model by using a correction coefficient calculated on the basis of a difference from a measured value. The table creation unit creates a table indicating a relationship between the load of t
