弾性長軸の完全浮上を目指すアクティブ磁気軸受システムの開発

抄録

This paper proposes non-contact control of supporting of an elastic long shaft by using active magnetic bearing (AMB) system. We aimed to develop a magnetic bearing system that takes dynamic of the elastic body into consideration An experimental system supporting the shaft with two AMBs is built and control experiments are carried out. As a first trial simple Proportional-Derivative (PD) feedback controllers are applied and levitation of the shaft is succeeded, While the 1st elastic mode of the shaft is appeared but undamped.
