Controller training based on historical data

A method of controlling a continuous process, comprising:

• operating a continuous process under control of a controller;
• during the operation of the continuous process, monitoring a value of a controlled variable of the continuous process;
• during the operation of the continuous process, at a given current time point, operating a predictor, which estimates a value of the controlled variable at a future time point, a plurality of time points ahead of the given current time point, by:
• initializing a prediction state with a state of the continuous process at the given current time point;
• interchangeably performing for the time points from the given current time point to the future time point:
• operating the predictor on the prediction state to estimate a value of the controlled variable in a next time point;
• and
• applying the controller to the prediction state including the values of the controlled variable in the next time point, from the predictor, to update the prediction state;
• and
• displaying a graph of the monitored value of the controlled variable along with the estimates of the value of the controlled variable from the predictor.
