Title PREDICTED VALUE MODIFICATION SYSTEM, CONTROL SYSTEM, PREDICTED VALUE MODIFICATION METHOD, CONTROL METHOD, AND PREDICTED VALUE MODIFICATION PROGRAM
Abstract Provided is a predicted value modification system that calculates a control value with higher accuracy (closer to a target value) by modifying a predicted value. A prediction governor (20) that calculates a control value (v) for controlling a control object (12) is provided with: a result value acquisition unit (22) that acquires a past target value of the control object (12), i.e., a result value (r(t-1)); a predicted value acquisition unit (21) that acquires a predicted value (r^(t)) obtained by predicting a target value of the control object (12); and a control value calculation unit (23) that calculates, by correcting the predicted value (r^(t)) by applying the result value (r(t-1)) and the predicted value (r^(t)) to a predicted value modification algorithm (G), a control value (v(t)) for controlling the control object (12). The predicted value modification algorithm (G) uses a parameter of a control model (P) of the control object (12).
