Stiction in control valves is the most common and long standing problem in industry, resulting in oscillations in process variables which subsequently lowers product quality and productivity. Developing a method to detect valve stiction in the early phase is imperative to avoid major disruptions to the plant operations. In this paper, nonlinear principal component analysis (NLPCA)-based stiction diagnostic tool is presented. Results from simulated case studies show that with proper quantification analysis, NLPCA shows a very promising capability for stiction diagnosis. © 2008 IEEE. date: 2009 official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-64949126466&doi=10.1109%2fICACC.2009.132&partnerID=40&md5=752cc8fd3261a9a96797c2935e9aa651 id_number: 10.1109/ICACC.2009.132 full_text_status: none publication: Proceedings - International Conference on Advanced Computer Control, ICACC 2009 place_of_pub: Singapore pagerange: 468-472 refereed: TRUE isbn: 9780769535166 citation: Zabiri, H. and Ramasamy, M. and Teh, I.S.Y.
