| Abstract: | Stiction is the most common problem in control valves, which causes oscillations in industrial control loops A new method to detect valve stiction for diagnosis of oscillations was proposed. The method which was easy to implement online could be used for both self-regulating processes and integrating processes, while most of other methods could only be used for neither self-regulating processes or integrating processes. The effectiveness of the proposed method is demonstrated with both the study of simulation and industrial examples. |
