PROBLEM TO BE SOLVED: To provide a model predictive control device, which may cope with increasing processing loads and keep robustness. SOLUTION: The model predictive control device 1 comprisies a feedback processing unit 50 to feed back an actual measured value or a controlled variable of a controlled object 2, and corrects a retrieving range or a predicted value in a unit 10 for retrieving an optimal operational variable as well as an estimated value in an unit 20 for estimating an internal state based on the actual measured value. That means, a duplicated computation is eliminated by setting a range for calculating an operational variable, which is derived from a unit for computing a candidate for operations (FB1), based on the fed back state value or the actual measured value. An accuracy for prediction is enhanced by correcting a candidate for the operational variable that is input into a unit 13 for predicting models and a controlled variable as an output for the unit 13 or an optimal controlled value which is input into the controlled object (FB2-5), and also by correcting an output from the unit 20 for estimating the internal state (FB5, 6).
