METHOD AND SYSTEM FOR MONITORING CONTROL VARIABLE OF MULTIVARIABLE PREDICTION CONTROLLER IN INDUSTRIAL PLANT

摘要

PROBLEM TO BE SOLVED: To provide a dynamic display and a method and system for monitoring a control variable in an industrial plant.;SOLUTION: An embodiment of the present disclosure relates to a method and system for monitoring a control variable of a multivariable prediction controller in an industrial plant. The method includes a step for receiving from a data source a predetermined adjustment parameter and at least one gain value to the control variable. The method further includes a step for obtaining a relationship indicator value by a processing unit based on a predetermined function. Inputs to the predetermined function are the received predetermined adjustment parameter and at least one gain value. The relationship indicator value provides information on a relationship between the control variable and a related process variable that influences the control variable. The control variable, the related process variable that influences the control variable, and obtained relationship indicator value are displayed on a GUI by which an operator monitors the control variable.;COPYRIGHT: (C)2015,JPO&INPIT
