In the conventional method, the influence of rotor flux variation is eliminated by the estimation system; however, the variation in inductance is not considered. By using the proposed method, inductance variation can be compensated online with the VDOB_AR. In addition, the gains of the VDOB_AR are turned by the estimated value to compensate for the resistance variation depending on motor conditions. The effectiveness of the proposed method is verified by experiments and the analysis of the factors related to the voltage disturbance.本誌: IEEJ Journal of Industry Applications Vol.9 No.4 （2020）本誌掲載ページ: 341-350 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/9/4/9_341/_article/-char/ja/ Show more
