Abstract
This paper proposes a method for calculating degaussing current based on the IGRF-14 model.The proposed scheme utilizes the International Geomagnetic Reference Field 14th Generation(IGRF-14),issued by the International Association of Geomagnetism and Aeronomy(IAGA),to compute the geomagnetic field at any geographic coordinate on the Earth using spherical harmonic analysis mathemeatical method.Subsequently,the induced magnetic field in the ship's coordinate system is calculated by transforming coordinates based on the vessel's heading,roll,and pitch angles.Finally,by offline training the model through backpropagation neural network,the compensation currents of the demagnetizing winding can be quickly calculated.The entire calculation process can be automatically realized via computer programming.The proposed degaussing current calculation method is concise and practically operable.关键词
