Control Performance Management in Industrial Automation provides a coherent and self-
contained treatment of a group of methods and applications of burgeoning importance to the …

The presence of non-linearities, such as stiction and deadband, places limits on the
performance of control valves. Indeed, in the process industries, stiction is the most common …

This article reviews advances in detection and diagnosis of plant-wide control system
disturbances in chemical processes and discusses new directions that look promising for the …

Many control loops in process plants perform poorly because of valve stiction as one of the
most common equipment problems. Valve stiction may cause oscillation in control loops …

Stiction or high static friction is a common problem in spring-diaphragm type control valves,
which are widely used in the process industry. Recently, there have been many attempts to …

Eight different models to represent the effect of friction in control valves are presented: four
models based on physical principles and four empirical ones. The physical models, both …

The importance of evaluating valve conditions and detecting the onset of possible
malfunctions is recognized as a key issue in control performance monitoring, as they may …

This contribution presents a new procedure for quantifying valve stiction in control loops
based on global optimisation. Measurements of the controlled variable (PV) and controller …

In 2006, Paul W. Holland retired from Educational Testing Service (ETS) after a career
spanning five decades. In 2008, ETS sponsored a conference, Looking Back, honoring …

In this paper, a novel and effective stiction detection method is proposed by combining K-
means clustering and the moving window approach. As a byproduct, the proposed stiction …
