Abstract

Flow rate soft sensors have become an important alternative for costly hardware flow meters, as they can estimate the flow rate with sufficient precision from easily measurable variables by using models and state estimation algorithms. This paper addresses the fundamental challenge that arises from ambiguous estimation problems, where the measured variable corresponds to two or more possible flow rate values. We develop and implement a decision algorithm that yields correct results in an industrial setup with substantial measurement noise. The results demonstrate a reliable flow rate estimation, providing a viable solution for real-time flow monitoring in centrifugal pumps with complex characteristics.

一种用于复杂特性泵的流量软传感器

流量软传感器可以利用模型和状态估计算法从容易测量的变量中获得足够精度的流量，已成为昂贵的硬件流量计的重要替代方案。本文解决了由模糊估计问题引起的基本挑战，其中测量变量对应于两个或多个可能的流量值。我们开发并实现了一种决策算法，该算法在具有大量测量噪声的工业设置中产生正确的结果。结果表明，该方法的流量估计是可靠的，为具有复杂特性的离心泵流量实时监测提供了可行的解决方案。
