The vehicles of the superconducting magnetically levitated transport (Maglev) system that travel at ultra-high speeds consist of lightweight car bodies, resulting in vibrations of relatively high frequencies. These vibrations are a source of concern with respect to the influence on ride comfort. The linear generator system which generates onboard power for the Maglev vehicle can also generate additional electromagnetic forces that can be used to control vibrations in the primary suspension between the bogies and guideway. This primary suspension control system, which was developed and tested in experiments of a full scale Maglev vehicle, were confirmed to effectively apply electromagnetic damping directly to the primary suspension, and reduce vibrations of relatively higher frequencies that are otherwise difficult to reduce by controlling only the secondary suspension. A computational Maglev vehicle model is used to examine the effectiveness of reducing vibrations by applying this primary suspension control.
