This paper proposes the experimental stabilization of electrodynamic maglev systems by means of passive components, providing key technological support for the Hyperloop concept of high-speed and sustainable transportation.
The pursuit of novel, environmentally friendly solutions for mobility and transportation has been a relevant area of technical and scientific progress in recent years. In this regard, the Hyperloop concept is a novel solution for sustainable transportation of people and goods at high speed. The electrodynamic levitation system in Hyperloop represents a key enabling technology. Nevertheless, its unstable nature is crucial and requires proper analysis and understanding. This paper proposes the experimental stabilization of electrodynamic maglev systems by means of passive components. A downscaled test setup is used to validate the numerical models that govern passive maglev systems. Setups for quasi-static and dynamic testing are proposed. The former experiments lead to model parameter tuning. The latter reproduce unstable behavior and assist in testing a stabilization method. Results in the time and frequency domains are used to analyze the system response and validate the proposed approach.
