This paper proposes a convolutional integration-based second-order differential calculation to identify the parameters of IPMSMs for a high-performance positioning servo system in an adaptive scheme. In addition, we propose a high-frequency voltage injection strategy considering the trade-off between acoustic noise suppression and estimation performance. The effectiveness of the proposed second-order differential calculation calculation method, and the high-frequency voltage injection for the acoustic noise suppression is verified experimentally.本誌: IEEJ Journal of Industry Applications Vol.10 No.1 （2021） Special Issue on “Motor Drive and its Related Technologies”本誌掲載ページ: 2023/01/10 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/10/1/10_19012766/_article/-char/ja/ Show more
