1. A plant control device, comprising:
a feedback controller that determines a control input of a plant by feedback control so as to bring an output value of a control amount of the plant close to a target value; and a reference governor that calculates a future predicted value of a specific state quantity of the plant by using a model of a closed loop system including the plant and the feedback controller, and corrects the target value that is given to the feedback controller based on the predicted value and a constraint that is imposed on the specific state quantity, wherein the reference governor searches for an optimal value of an evaluation function that is expressed by an objective function with a corrected target value candidate as a variable, and a penalty function that adds a penalty to the objective function when the predicted value conflicts with the constraint, and determines a corrected target value candidate that optimizes the evaluation function as a corrected target value. |
