Active magnetic bearing (AMB) is a complex system which integrates mechanism, electricity and magnetism. Aimed at the asymmetry and strong coupling bearing structure, a design method of controllers based on the current distribution of bearing magnetic poles is suggested in this paper. This method divided the customary controller into two parts: the feedback adjuster and the current distributor so the design of controller is predigested. In this paper, the magnetic pole current distributor is discussed and designed, which can be applied to a cone-magnetic bearing system.
