Control valve (CV) is one of the important final control elements. If CV unintendedly takes control action because of its internal failure, the process becomes unstable, at worst, industrial accidents occur. Stiction is the most commonly occurred as the internal failure of CV. However, it has been difficult to detect the stiction, because operators have not been able to get the internal information of CV from traditional instrumentation. In these latter days, Fieldbus has been widely implemented. It is possible to get the internal information by using Fieldbus instrumentation. In this study, we developed a method for stiction detection of pneumatic control valve via Fieldbus communication. The effectiveness of the detection method was demonstrated by the laboratory equipment with the flow control system.

控制阀是重要的末级控制元件之一。如果CV由于内部故障而无意中采取控制措施，则过程变得不稳定，最坏的情况是发生工业事故。静摩擦是CV最常见的内部失效形式。然而，由于操作人员无法从传统的仪器中获得CV的内部信息，因此很难检测到静摩擦。近年来，现场总线得到了广泛的应用。现场总线仪表的使用使获取内部信息成为可能。本文提出了一种基于现场总线通信的气动控制阀静摩擦力检测方法。该检测方法的有效性通过具有流量控制系统的实验室设备被证明。
