A Study on Indirect Suspension of Magnetic Target by Actively Controlled Permanent Magnet

This paper discusses an indirect suspension of magnetic target through an actively controlled permanent magnet. This proposed system consists of an electromagnet, a permanent magnet and a target mainly. The dynamics of levitated bodies are restricted in one dimension, and the target issufficiently away from the electromagnet. The target is suspended by a proportional - derivative control with respect to the position and the velocity of the permanent magnet. The aim is to model the dynamics of levitated bodies by magnetic charges. The behav-iors of levitated bodies near the reference positions are studied numerically and experimentally. As a result, it is shown that the behaviors of levitated bodies near the reference positions can be described by the proposed model.
