Abstract: The high-precision suspension control problem of EMS maglev trains is studied. Firstly, considering the elastic connected structure of the suspension electromagnet, suspension frame, and vehicle body, as well as the bridge dynamics containing high-order vibration components, a trail coupled vertical motion model is es-tablished. Then, the integrators serial system structure from input voltage to suspension gap is analyzed and an active disturbance rejection suspension control design is proposed. Meanwhile, the acceleration feedback de-sign of suspension electromagnetic is adopted to increase the attenuation speed of vertical acceleration oscilla-tions in various parts of the train, the comfort is enhanced. The closed-loop stability results are provided for the proposed method. Finally, simulation verification is conducted for periodic disturbances and parameter perturbations of rails.
