CONTROL DEVICE OF PLANT, PLANT, CONTROL METHOD OF PLANT, AND COMPUTER READABLE STORAGE MEDIUM RECORDING CONTROL PROGRAM OF PLANT
First Claim
1. A control device of a plant which controls operation amounts of a plurality of types of equipment constituting the plant, the control device comprising:
- a prediction model deriving unit that derives a prediction model to which a measurement value measured at the plant is input, and from which a monitoring target value which is a value to be monitored is output;
an adjustment amount calculating unit that calculates the operation amounts of a plurality of types of the equipment in a case where the monitoring target value which is to be output becomes a desired value, and calculates differences between the operation amounts of existing control and the calculated operation amounts as first adjustment amounts;
a constraint condition setting unit that sets a constraint condition of the operation amounts of a plurality of types of the equipment based on the measurement value and an operation condition of the plant when the measurement value is measured; and
an operation amount calculating unit that calculates second adjustment amounts obtained by correcting the first adjustment amounts by applying the set constraint condition for each of a plurality of types of the equipment and calculates a plurality of the adjusted operation amounts based on each of the calculated second adjustment amounts.
