Stability analysis of maglev elastic vehicle-guideway-coupled system

It was found in research that the relative position between the maglev vehicle and the guideway makes some effects on the stability of maglev system. To make this problem clear, a preliminary study of this problem was made in this paper on the condition that the guideway was a single-span guideway. A vehicle-guideway-coupled model for double suspension magnets was introduced, and root locus analysis method was used to analyze the influence that the relative position between the maglev vehicle and the guideway made on the closed-loop poles of the maglev elastic vehicle-guideway-coupled system. The result that was found could be helpful for the design of the maglev controller.
