走行弾性ベルトの磁気浮上制御

抄録

A method of magnetic levitation control of a traveling steel belt is presented. A traveling steel belt is supported in contactless manner by attractive forces of electromagnetic actuators which are controlled by feedback signals from gap sensors to stabilize the levitation behavior. A sub-optimal control theory is applied to minimize effects of spillover of residual vibration modes of the belt. To verify the usefulness of the method, an experiment of digital control was performed using a SUS430 steel belt.
