The development of electronic equipment manufacturing industry requires increasingly higher levels of integration density; hence, not only stage position but also the stage attitude needs to be controlled rapidly and precisely. The attitude is determined on the basis of roll, pitch, and yaw motions, which are affected by the nonlinearity and coupling arising from Euler's equation and coordinate rotation. These effects degrade the attitude control performance. This paper proposes a multi-input multi-output nonlinear feedforward attitude controller which compensates for these effects. The effectiveness of the proposed approach is verified through simulations and experiments.本誌: 電気学会論文誌D（産業応用部門誌） Vol.134 No.3 （2014） 特集：産業計測自動制御，メカトロニクス制御本誌掲載ページ: 293-300 p原稿種別: 論文／日本語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejias/134/3/134_293/_article/-char/ja/
