This paper describes a novel planar repulsive maglev prototype. In this maglev system, the carrier is levitated by a planar 2D array of coils. The levitation forces are due to repelling between the magnets and the coils. Then, the general model of motion of the carrier with complete degree of freedoms(DOFs) is derived and analyzed. Next, for the sake of control, a PID controller is designed here to regulate the all DOFs of the planar maglev system. From the simulation results, satisfactory good performances including stiffness and precision have been demonstrated. The experiment of the proposed system is under preparation.
