摘要
A system, method, and an apparatus relating to data collection regarding valve movement over a period of time in order to determine the effects of stiction on the valve. With data collection done over a period of time, it is possible to remove dependency on a high speed method of data collection. The evaluation of the valve movement includes consideration of a manipulated variable (MV) for diagnosis, or detection, of stiction of the valve.
