Abstract

The work focuses on experimental and theoretical examination of the influence of the distortion signals generated by the inverter and the active magnetic bearing (AMB) dc link voltage on an AMB control system. These low-frequency disturbances may result in performance degradation or lead to an unstable system. The analysis and measurements are performed on an AMB system controlled by an H _∞ controller. The studied signals include positions and currents in 5DOF, AMB dc link voltage, drive currents, and acceleration of the stator frame.
