A d/q axis flux map and the non-linear torque characteristics of wound-field motors were estimated using a single layer neural network to reduce the number of finite element analysis and load tests. Moreover, to improve estimation accuracy even with a small number of learning data, training data-set to be input into machine learning were selected based on a Bayesian approach. The proposed method improves the estimation accuracy compared to that of the conventional data-driven method. The proposed method is validated by applying it to the numerical and experimental problem. Moreover, estimated results are compared with those of the conventional methods.本誌: IEEJ Journal of Industry Applications Vol.13 No.3 （2024）本誌掲載ページ: 338-345 p原稿種別: 論文／英語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejjia/13/3/13_23012206/_article/-char/ja/ Show more
