摘要:

为得到理想的风机特性曲线,文中结合实际,在传统方法的基础上,提出了回归分析法,并在Matlab环境中对实测数据进行建模仿真,比较回归效果,得到了较为理想的风机特性曲线,消除了在以往特性曲线中存在的拟合曲线不光滑,回归效果不佳等问题,可有效地反映出厂风机的性能。

Abstract:

The regression analysis method is proposed for obtaining the ideal fan characteristic curve in this paper. Matlab modeling and simulation is performed based on the measured data. The regression results are compared to yield the ideal fan characteristic curves, avoiding the nonsmooth fitting curves and poor regression effect by the conventional methods and effectively reflecting the performance of the factory fan.

Key words: fan characteristics, regression analysis, polynomial regression, multi element linear regression
