磁気軸受を用いた弾性長軸の非接触アクティブ制振

抄録

This paper discusses on non-contact vibration control of an elastic long shaft by using active magnetic bearing (AMB) system. An experimental system is built. An elastic shaft is supported by two ordinary bearings with an AMB is located in the middle of the shaft to suppress vibration computer simulation and control experiments are carried out. As a first trial simple Proportional-Derivative (PD) feedback controllers are applied and vibration suppression of the shaft is succeeded, as for rest shaft.
