A model predictive control (MPC) device includes an input interface configured to receive an industrial process input associated with at least one component of a process automation plant, an output interface configured to transmit a control instruction to control the component, memory configured to store first and second MPC process models corresponding to different states, and a processor configured to identify a current state parameter of an industrial process, and predict a future industrial process output using the first or second MPC process model, based on the current state parameter being associated with the first or second MPC process model. The processor is configured to calculate a target operating point according to the predicted future industrial process output, determine a control signal to drive the industrial process to the calculated target operating point, and output the determined control signal to control operation of the component of the industrial process plant.

A system for predicting control factors for a manufacturing facility, performed by at least one processor, includes: a model execution management unit configured to execute or manage one or more facility control factor prediction models trained to predict control factors for a manufacturing facility received from a prediction model providing system, a storage unit configured to store data associated with the facility control factor prediction models, and a communication unit configured to receive an independent factor of one of a plurality of manufacturing facilities from a facility control system, and configured to transmit a control factor predicted value calculated by one of the one or more facility control factor prediction models based on the independent factor to the facility control system.

A control system, for controlling an injection amount of a reducing agent injected into exhaust gas flowing from a coal-fired boiler in a thermal power generation facility toward a denitrification reactor of a denitrification device, includes: a first predictor predicting a first concentration of nitrogen oxides in the exhaust gas flowing toward the denitrification reactor based on first operation data of the thermal power generation facility; and a control device controlling the injection amount based on a predicted value of the first concentration. The first operation data includes at least either one of second operation data and third operation data, the second operation data being operation data of one or more coal pulverizers provided in the thermal power generation facility, and the third operation data being operation data of the coal-fired boiler affected by variation in operation conditions of the one or more coal pulverizers.
