In this paper, we propose an effective modeling and controller design scheme for the three-pole hybrid-type AMB recently develped in the laboratory, which consists of three permanent magnets, providing bias flux, and three Hall diodes, measuring rotor displacements. Along the three physical coordinates formed by three poles, we introduce the redundant coordinate system to design three identical decoupled controllers. The experiments are also carried out in order to verify the effectiveness of the proposed controller in stabilizing the transient and steady state responses of rotor.
