Orthogonal Polynomial Fitting for Pump Characteristic Curves

ZHOU Long-cai, QIU Chuan-xin (School of Water Resource and Hydropower, Wuhan University, Wuhan, Hubei 430072, China)  
Orthogonal polynomial is used to fit the characteristic curves of pump with rand om data to avoid the ill-conditioned system of equations that probably appears i n ordinary polynomial fitting. The Forsythe Recurrence Method is adopted to gene rate the orthogonal polynomial, and the degree of the polynomial is determined b y significance test. Using drawing program to make intuitive analysis for the co mputation, the method is shown to be practical by several actual examples.
