CONTROL SYSTEM WITH HIERARCHICAL SYSTEM IDENTIFICATION

Abstract: a predictive control system for a plant includes a model generator and a controller. the model generator is configured to train a subprocess model representing a subprocess of the plant using historical values of forecast variables and manipulated variables. the model generator is further configured to train a main process model representing a main process of the plant using historical values of controlled variables, forecast variables, and manipulated variables. the controller is configured to execute a predictive control process using the subprocess model and the main process model to control operation of the plant. the predictive control process includes using the subprocess model to predict future values of the forecast variables, using the main process model to predict future values of the controlled variables based on the predicted future values of the forecast variables, and controlling operation of the plant based on the predicted future values of the controlled variables.
