This study revealed that the joint angle/voltage relationship can be modeled as a fourth-order system. This enables the inclusion of a time delay in the high-order phase delay of the force/voltage relationship, which may lead to delay recovery using a suitable controller. Accordingly, a full state feedback controller is proposed in this study, to recover the phase delays. Jerk measurement is mandatory for full state feedback controllers owing to the joint the fourth-order joint angle/voltage relationship. This issue can be solved by the recent development of high-resolution encoders. Finally, the validity of the proposed method was verified experimentally.本誌: IEEJ Journal of Industry Applications Vol.10 No.2 （2021） Special Issue Ⅰ on “Motion Control and its Related Technologies” Special Issue Ⅱ on “Advanced Power Electronics Technologies”本誌掲載ページ: 124-133 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/10/2/10_20004260/_article/-char/ja/
