This paper presents the application of an LQ controller to an active magnetic bearing system (AMB).}, abstract={Two control strategies are presented and compared: local and global. In the first case the rotor is modelled as two separated masses located at the bearing. In the second case rotor stabilization is considered globally as a problem of the rotating rigid body suspended in a magnetic field. The second approach is especially important for high-speed rotating machines. The control performance of both algorithms was analysed using an experimental AMB laboratory system.}, type={artykuł}, title={Comparison of linear control methods for an AMB system}, keywords={active magnetic bearing, real-time control, modelling, LQ control, control performance}, }
