An axial flux permanent magnet motor (AFPMM) is a permanent magnet motor with a novel structure, equipped with higher efficiency and torque density than a traditional radial flux motor. In this paper, a position tracking controller based on fuzzy sliding mode control is presented and applied to an AFPMM servo system. High torque capability at a relatively low and large speed range is achieved. Fuzzy sliding mode control weakens chattering in sliding mode control, and helps the system meet the requirement for high accuracy in servo system. A simulation model is constructed based on a Matlab/Simulink platform. The numerical results confirm that the proposed control system can track given signals accurately with desired control performance.
