N2 - As one of the problems of the rotary machine, unbalance vibration caused by the unbalance of the mass of the rotor, the electromagnetic force in the TMP, and the position of the AMB is well known. Peak-of-Gain Control (PGC) and Automatic Balancing System (ABS) have been reported as the compensation methods of the unbalance vibration, This paper considers the new compensation method for unbalance vibration of five-axes active magnetic bearing systems. The proposed Phase-Variable Control (PVC), which is a phase stabilization method, consists of the cascade connection of the PGC and ABS. By using this compensator, only the phase of a control system can be adjusted. It leads to the whirling suppression of a rotor. The performance of the proposed and conventional unbalance vibration compensators is compared by experiments on the rotational test of a turbo molecular pump.
