On the other hand, they have a problem in that the amplitude decreases significantly in response to an external load. To overcome this problem, the effectiveness of PID control using back electromotive force (EMF) in maintaining a constant amplitude against an external load is investigated. This paper proposes a numerical method involving the use of the 3-D finite element method to analyze the dynamic characteristics of LRA when it is operated under PID control in PWM feedback control by using the back EMF detected from a coil. The effectiveness of this method is shown through measurements obtained by using a prototype.本誌: IEEJ Journal of Industry Applications Vol.1 No.2 （2012）本誌掲載ページ: 111-116 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/1/2/1_111/_article/-char/ja/
