Abstract

A computer based method for controlling an industrial process that includes at least two unit processes, including the steps of directly controlling the process by a control model including one or more algorithms, and automatic diagnosis of the validity of the process data retrieved from the process for the purpose of preventing irrelevant process data from being used as an input in the control model.
