Shape-based Stiction Detection Using Area Calculations(0–100%). The chapter describes the method and the basis for its development and presents results from tests on a wide range of data sets. Also described are key assumptions and issues for practical implementation of the method.

Arresting

Stiction Estimation Using Constrained Optimisation and Contour Maped strategy not only detects but also quantifies valve stiction. The validity of the proposed method is illustrated through industrial examples. Also, the closed-loop identifiability issue is addressed.

Shape-based Stiction Detectionthey 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.

The Features of GTU Thermal Calculation. Some basic analysis tools will be described, including the input–output relation of valves under stiction and the describing function analysis. Data from typical industrial control loops are presented to illustrate the effects of stiction on the shape of loop signals, such as the process variable and the controller output.

CANE

A New Collision Cross Section Set for Silaneture (level control). For such loops, an alternative to cross-correlation needs to be offered. Such an approach that is signal-shape based is presented afterwards. Interestingly, the same approach can also be used for self-regulating (. non-integrating) loops as well.
