Zero Power Levitation Control with Gap Compensator of Hybrid Magnet Levitation by Load Observer

부하 관측기에 의한 공극 보상기를 포함한 제로파워 부상제어

This paper introduced the scheme that it improved performance of magnetic levitation system with zero power controller. Magnetic levitation is used widely, but it is complicated and difficult to control due to having nonlinear characteristics of gap and current. So, it is proposed a scheme considered changed gap according to variable load and is verified by simulation and experiments in this paper.
