A Comparative Study of Valve Stiction Compensation: Knocker Based Methods

Control valve stiction is one of the common issues in industrial plant leading to poor control loops performance. Knocker based methods is one of common stiction compensation approaches. In this paper, a detailed comparison is held among three knocker based methods. Ideal compensator criteria proposed by Srinivasan and Rengaswamy is used to perform the comparison between three methods using MATLAB simulation and experimental setup.
