Methods of diagnosing and analyzing the large-scale process automation control system

摘要

The invention provides methods for diagnosing and analyzing a large process automatic control system having multiple control loops. Evaluation of multiple key performance indicators that are multiple pre-defined for (KPI) is, control of each control loop, it is automatically generated for the section of the signal and process. Evaluation of the plurality of automatically generated KPI that multiple pre-defined, may be displayed graphical user interface of the computer (GUI). and may change the evaluation of multiple user has automatically generated a KPI that multiple pre-defined. Data different views may be displayed on the GUI as well. Series trend when more than one for the measured process variable, controller output, controller settings and not just the error, in the form of plots of the three-dimensional and two-dimensional data multiple views, controller parameters clustering multiple views I include the.
