The suspension system of the Electromagnetic Suspension (EMS) maglev train is crucial for ensuring safe operation. This article focuses on data-driven modeling and control optimization system. By Extended Dynamic Mode Decomposition (EDMD) method based Koopman theory, state input data are collected to construct a high-dimensional linearized model without detailed parameters system, preserving nonlinear characteristics. With model, LQR controller State Observer (ESO) applied optimize control....
In the practical application of high-temperature superconducting (HTS) magnetic levitation, influence ambient temperature on its performance is mainly reflected in change characteristics permanent magnet guideway (PMG). order to investigate PMG at high and levitation HTS bulk above, we studied three kinds six single (PM) range from room 85 °C. Furthermore, investigated effect this variation under a zero-field-cooling condition. The results show that N-S-S-N-type PMG-H has better field...
A new HTS maglev vehicle called "KENYON" that can carry 8 passengers was successfully developed in December 2019. The adopted the bogie structure of independent running gear, which brings improvement curve passing performance. In order to further optimize performance view small radius ring test line, corresponding experimental research carried out this paper. results show wheelbase and centripetal arrangement were beneficial improve vehicle's ability.
