능동 자기 베어링을 위한 PID 제어기의 설계 = DESIGN OF PID CONTROLLERS FOR ACTIVE MAGNETIC BEARING SYSTEM

다국어 초록 (Multilingual Abstract)

As many modern rotor systems tend to be operated at high speed, there is a lot of demand for the magnetic bearings which have high performance and very high rotating speed compared with rolling element bearings. The leading countries like France, Japan, Switzerland and U.S.A have already been arare of these merits of the magnetic bearings and have researched very actively in this field. In this study, we designed a PID control system for magnetic bearings based on the rigid body model and the frequency response method. We also simulated the stability, steady state performance and other dynamic performances of the designed magnetic bearing system. Finally, we designed and manufactured the 5-axis active magnetic bearing system and experimentally verified the numerical results.
