METHOD AND SYSTEM FOR MONITORING CONTROLLED VARIABLE OF MULTIVARIABLE PREDICTIVE CONTROLLER IN AN INDUSTRIAL PLANT

摘要

Embodiments of the present disclosure relates to a method and system for monitoring a controlled variable of a multi variable predictive controller in an industrial plant. The method comprises receiving predetermined tuning parameters and at least one gain value for the controlled variable from the data source. The method further comprises determining relationship indicator values by a processing unit based on predetermined functions. The inputs to the predetermined functions are the received predetermined tuning parameters and the at least one gain value. The relationship indicator values provide information about the relation between the controlled variable and the related process variables affecting the controlled variable. The controlled variable, related process variables affecting the controlled variable and the determined relationship indicator values are displayed on the GUI using which the operator monitors the controlled variable.
