However, the wear and tear of rubber tires after long-term operation can affect the safety of train operation, and frequent replacement will increase operational costs. To address the above issues, a new suspended structure for maglev trains based on electromagnetic levitation was designed, and this new suspension method was investigated. Firstly, the dynamic characteristics of the bogie structure were modeled and analyzed in the Cartesian coordinate system, and a decoupling control algorithm was designed to independently control the steering attitude angle and the suspension height. Secondly, to address the issue of model inaccuracy caused by simplification in the dynamic modeling process, a fuzzy sliding mode control strategy was introduced. In order to verify the suppression effect of fuzzy sliding mode control on system oscillation, a fuzzy sliding mode control model and a sliding mode control simulation model were set up. The simulation results showed that compared with traditional sliding mode control, fuzzy sliding mode control can greatly suppress oscillation phenomena.Finally, the correctness of suspension control strategy was verified through the construction of a scaled experimental model of the new suspended maglev train based on electromagnetic levitation. suspended train magnetic levitation decoupling control fuzzy slide film control Full Text Additional Declarations No competing interests reported.
