Bearingless permanent magnet synchronous motor (BPMSM) is a new electrical machine combining the characteristics of conventional PM synchronous motors and magnetic bearings. Most references about motor controller design have used mathematical models without considering the coupling between torque and magnetic suspension windings. Simulation results in this study have shown that response of system is unreasonable when these controllers are used in mathematical models with considering the coupling between two windings(more perfect model). Therefore, coupling consideration between two windings is an important aspect of controller design, in order to insure its proper performance. In this study, a new controller has been designed and proposed which considers the coupling between torque and magnetic suspension windings. Simulation results using Matlab/Simulink software have shown that magnetic suspension system remains stable when the reference signals from rotor radial displacements or the load torque suddenly change. Therefore, the simulation results show the effectiveness of proposed scheme.
