2003 (English)In: International journal of adaptive control and signal processing (Print), ISSN 0890-6327, E-ISSN 1099-1115, Vol. 17, no 7-9, 625-634 p.Article in journal (Refereed) Published
A method for detecting static friction (stiction) in control valves is proposed. The method is model-based and is inspired by ideas from the fields of change detection and multi-model mode estimation. Opposed to existing methods only limited process knowledge is needed and it is not required that the loop has oscillating behaviour. The advantage of the method is illustrated in both numerical simulations and evaluations on real loop data.
