Spectral Analysis

Spectral Analysis 2016-10-19T14:30:13+00:00

Apply innovative methods for examining data and gaining insight.

Hidden in your process data are frequencies that reveal a great deal.  Spectral analysis is a potent tool for examining frequency-based data and for identifying peaks shared by two or more PID control loops.  It empowers production staff to examine process interactions in an altogether different light and isolate unexpected sources of performance issues.

Power Spectrum is another advanced forensic tool within PlantESP.  It graphically displays a given control loop’s frequency peaks and easily identifies other loops that share similar frequency contours.  With Power Spectrum PlantESP uncovers insights that are often invisible to the naked eye.

PlantESP makes it easy to switch from one advanced forensic tool to another.  Control loops selected in the Power Spectrum viewer can be evaluated in the Cross-Correlation matrix with the touch of a button.
