Since research on high-speed and high-precise positioning control using a servo system using magnetic levitation technology has been carried out in the past, it is expected that position control of a rotational shaft with high precision is also expected in an active magnetic bearing(AMB), which is an application of magnetic levitation technology. In recent study, one of the application is the analysis of rotor dynamics in arbitrary orbits is considered. Therefore, it is necessary to design a control system that can track with high precision. In this paper, an arbitrary whirling orbit control system of AMB is proposed. In order to demonstrate the effectiveness of the proposed control system, tracking control experiments are carried out on the positions of the rotor axes of circular and elliptical orbits.
