However, inductances of IPMSMs with magnetic saturation, vary depending on the current; thus, obtaining the MTPA condition is difficult. This study developed an online MTPA angle search method for IPMSMs with cross-saturation. In the proposed method, a flux-linkage plane is modeled and the model parameters are identified using the recursive least squares (RLS) method. The proposed method searches for the optimum current phase angle (MTPA angle) achieving MTPA control based on the gradient ascent method using the parameters identified for the flux-linkage plane model. This study conducted various experiments to evaluate the performance of the proposed online MTPA angle search method. The effectiveness of the method was demonstrated.本誌: IEEJ Journal of Industry Applications Vol.13 No.4 （2024） Special Issue on “JIASC 2023”本誌掲載ページ: 400-408 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/13/4/13_23009975/_article/-char/ja/
