Thermodynamic analysis of the effect of reservoir temperature change on the performance of organic rankine cycle system on geothermal power plant AIP Conference Proceedings 1755, 110005 (2016) Abstract. The presence of static friction or stiction in a valve can lead to poor performance in industrial automation and control system. This paper presents a method to detect and quantify stiction based on normality test and Hammerstein system identification. Detection and quantification are showed by the and parameters, where the value of and greater than 0 indicate the valve suffer from stiction. The proposed method is implemented to a confirmed sets of industrial data as a validation. The result show that the proposed method can accurately detect the presence of stiction and distinguish it to other problem in control loops.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
