A Study on the Static Levitation Control of Magnetic Bearing using Optical Fiber Displacement Sensors

광파이버 변위 센서를 적용한 자기베어링 정적 부상 제어 연구

Five expensive sensors are necessary to control a magnetic bearing system. The sensor price rate of magnetic bearing system is high. So it is necessary that cheap and good sensor is developed. The optical fiber displacement sensor is adaptive to satisfy this condition. We can design magnetically suspended spindle based on static characteristic of optical fiber displacement sensor developed. The controller can be designed by decoupled feedback PD. Therefore, it is simpler than any other controller comparatively.
