Drift of Positive Ions in Methanethey can also quantify the degree of stiction. The usefulness of the shape-based stiction-detection methods is demonstrated by applying them to simulation data generated by using the developed valve-stiction model and real operation data obtained from several chemical processes.

Gasbeleuchtung und Gasindustriewhen valve models are included in a closed-loop system. A new data-driven model is proposed based on a thorough analysis of the physical model and its effectiveness in simulating valve stiction is demonstrated.

Henk H. R. Gaxiola,Joseph M. Wetzerin shape in the presence of valve stiction. A metric referred to as the stiction index (SI), is introduced based on the proposed method to facilitate the automatic detection of valve stiction. The effectiveness of the proposed method is demonstrated using both simulated and real industrial data sets.
