N2 - In this contribution a new approach to control a rubbing rotor system is presented. The control forces are applied on the rotor in case of rubbing indirectly via the auxiliary bearing, which is mounted on two electromagnetic actuators in a 45 degrees alignment. Using the high band-width of output of these actuators, which have been developed at the Institute of Applied Mechanics, a model based two phase feedback control allows a significant reduction of the forces during rubbing. For the experimental verification of the designed control system a test rig has been implemented. Measurements of a first approach are presented, showing a reduction of the contact forces up to 80 percent. The developed control system of the auxiliary bearing is able to reduce the load of the whole system significantly.
