Abstract: A predicted value shaping system is provided for calculating a highly accurate control value by shaping of a predicted value. A prediction governor for calculating a control value (v) for controlling a controlled object includes: a result value acquisition unit (22) that acquires a previous target value of the controlled object, that is, a result value (r(t−1)); a predicted value acquisition unit (21) that acquires a predicted value (r (t)) obtained by predicting the target value of the controlled object (12); and a control value calculation unit (23) that calculates a control value (v(t)) for controlling the controlled object (12) by applying the result value (r(t−1)) and the predicted value (r (t)) to a predicted value shaping algorithm (G) to correct the predicted value (r̂(t). The predicted value shaping algorithm (G) uses parameters of a control model (P) of the controlled object (12).

Abstract: A predicted value shaping system is provided for calculating a highly accurate control value by shaping of a predicted value. A prediction governor for calculating a control value (v) for controlling a controlled object includes: a result value acquisition unit that acquires a previous target value of the controlled object, that is, a result value (r(t−1)); a predicted value acquisition unit that acquires a predicted value (r^(t)) obtained by predicting the target value of the controlled object; and a control value calculation unit that calculates a control value (v(t)) for controlling the controlled object by applying the result value (r(t−1)) and the predicted value (r^(t)) to a predicted value shaping algorithm (G) to correct the predicted value (r^(t). The predicted value shaping algorithm (G) uses parameters of a control model (P) of the controlled object.
