Method For Detection Of Diagnosing Control Valve Stiction

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. 本申请提供了涉及与段时间内的阀门移动有关的数据采集的系统、方法和设备，用于确定粘滞对阀门的影响。利用在段时间内进行的数据采集，可以消除对高速数据采集方法的依赖。对阀门移动的评估包括对用于阀门粘滞的诊断或检测的操纵变量(MV)的考察。
