高斯-牛顿法在含铁芯线圈磁化曲线转换问题中的应用

The Application of Gauss-Newton's Method to Conversion for Magnetizing Curve of Iron Core Coil

提出了应用高斯-牛顿法进行转换的方法,指出只注意对V-A特性曲线的拟合精度,而不注意φ-i曲线的计算误差是不够的,并以算例说明本文方法无论是拟合精度还是计算的φ-i曲线与实际磁化曲线的吻合程度均优于其它方法。

A method to make conversion by Gauss-Newton's method is proposed in this paper. The writers point out that it is not perfect enough not to lay stress on computing error of (?)-i curve but on fitting accuracy of V-A characteristic curve. Calculated Example shows that this method is preferable to other conversion methods both in fitting accuracy and in the degree that the calculated (?)-i curve approaches the real magnetizing curve.
