移动最小二乘法在水泵性能曲线拟合中的应用
Application of Moving Least Square Method in Curve-Fitting of Pump Performance
摘要
Abstract
This paper introduced the principle of moving least square(MLS) method and its application in fitting pump performance curves. The error of the MLS method was about one-tenth of that of the conventional least square method after a comparison using case studies between two methods. The results showed that moving least square method had high accuracy when it was used in curve-fitting of pump performance, especially in the unstable areas of axial-flow pumps. It has great significance for the research of four-quadrant pump performance curve-fitting and transition simulation.关键词
