A Novel Synchronous Rotating Frame Transformation for Complete Synchronous Vibration Force Suppression
Unbalance vibration force is critical in normal operation of magnetic bearings.Among all vibration forces,the synchronous vibration force is the most influential factor.To effectively suppress the unbalance force caused by the mass unbalance of high-speed magnetic suspend rotor,in this work,a novel method for active magnetic bearings based on the synchronous rotating frame(SRF)transformation is adopted.In this case,the magnetic bearing force is directly set as the input of the SRF transformation.The structure and principle of SRF transformation is proposed.In order to maintain the system stability,stability analysis which is related to the SRF transformation is conducted.In order to ensure the stability of the whole close-loop system,only one parameter needs to adjust.Simulation results show that the proposed method can effectively suppress synchronous vibration force.Compared with the conventional method of vibration force suppression the method proposed has batter performance.
