The method involves measuring process variable values, predicting future deviations of a process variable relative to the measured value, generating a control signal based on the prediction with a first control rule, measuring a process fault, predicting future deviations in process variables related to the fault without recourse to the measured value and generating a control signal based on the prediction with a second control rule. The method involves measuring the values of at least one process variable, predicting future deviations of a process variable relative to the measured value of the variable(s), generating a control signal based on the prediction with a first control rule, measuring a measurable fault in the process, predicting future deviations in process variables related to the fault, but without recourse to the measured value of the process variable(s), and generating a control signal based on the prediction with a second control rule. Independent claims are also included for the following: a computerized system for controlling an industrial process and a computer program code element.
