Title Of Article :
A simple method for detecting valve stiction in oscillating control loops
Latin Abstract :
This paper presents a simple and new method for detecting valve stiction in an oscillating control loop. The method is based on
the calculation of areas before and after the peak of an oscillating signal. The proposed method is intuitive, requires very little computational
effort, and is easy to implement online. Analytical results are derived to show the theoretical basis of the new method and
field results are presented to show its effectiveness on real world control loops.
