Most initial position estimation methods utilize the amplitude or differential values of high-frequency currents, and the performance of sensorless control depends on the algorithm to reconstruct these values. Although Fourier series expansion, which requires some low-pass filters (LPFs), is utilized generally, the filters degrade the response of position estimation. This paper focuses on the algorithm for initial position estimation of IPMSMs at standstill, and proposes a new algorithm using comb filters that can rapidly calculate the amplitude values of high-frequency currents and improve the initial position estimation performance. In addition, this paper experimentally shows the performance of the initial position estimation, starting characteristics of sensorless control, and characteristics of sensorless control including standstill under the load.本誌: IEEJ Journal of Industry Applications Vol.4 No.3 （2015） Special Issue on “IPEC-Hiroshima”本誌掲載ページ: 204-211 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/4/3/4_204/_article/-char/ja/ Show more
