However, the amplitude of LRAs severely decreases when external load is applied. To solve this problem, we applied PID (Proportional-Integral-Derivative) control to an LRA, and the mover amplitude remained constant against an external load. When a large external load was applied with the target voltage of PID control high, however, input power reached maximum and the amplitude did not follow the target value. As a solution, it is effective to utilize electrical resonance and generate large current. In this paper, we propose a control method to generate an electrical resonance. The effectiveness of the proposed method was verified through dynamic characteristic analysis employing two-dimensional finite element method and measurements.本誌: IEEJ Journal of Industry Applications Vol.7 No.2 （2018） Special Issue on “Motion Control and its Related Technologies”本誌掲載ページ: 175-180 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/7/2/7_175/_article/-char/ja/
