Abstract

This paper introduces a control method using a ring magnet for the stable levitation of a cylindrical ferromagnetic object. The levitation has a strong stability with anti-disturbance abilities, and weight can be placed on the floating magnet. The magnetic field created by the ring magnet provides stabilities in 3 degrees of freedom of the floating magnet, and a feedback control in the horizontal plane is introduced to the control system. Analytical calculation and experiments have been done to prove the feasibility of this control method.
