Identification of Mass Unbalance and Sensor Runout on a Rotor Equipped with Magnetic Bearings
In this paper, we propose a new identification method of the sensor runout and the unbalance on a rigid rotor supported by active magnetic bearings applying the incremental least square on-line method and perform some numerical simulations on the their identification applying to a rigid rotor model of a turbo-molecular pump. The paper also presents some results on the identification accuracy and effects of the rotor model error. From the numerical simulations we conclude that the proposed identification method is effective for the simultaneous identification of the unbalance of rotor and the sensor runout.
