Abstract: The modeling and accurate control research on inverse system theory combined with model reference adaptive control method was proposed for an axial hybrid magnetic bearing, which is a nonlinear system. Based on introduction of the configuration of the axial hybrid magnetic bearing, set up the equations of the hybrid magnetic bearing, and the analytical inverse system of the hybrid magnetic bearing was obtained by analyzing the reversibility of the mathematical model, and then inverse system and original system were in series to constitute pseudo linear systems. Finally, a controller of the pseudo linear systems was designed by using model reference adaptive control method. The simulation results show that this kind of control strategy can realize linearization mathematical model of the axial hybrid magnetic bearing,  the new model can operate well according to the perfect performance indicators, and the whole control system has good dynamic and static performance.
