Research on Dynamic Control of Maglev Suspension System

In this paper, electromagnetic dynamic characteristics of suspension system of middle-low speed Maglev train are analyzed with hybrid simulation method. The structure of Maglev rolling stock and suspension system is introduced, and the finite element analysis(FEA) method is applied in calculating the coupled rail-electromagnet pair. Dynamic model of rail, electromagnet and controller is established, combine the FEA result and component model into a hybrid simulation model. The simulation results demonstrate that both the FEM analysis feedback and the controller run normally in the hybrid model. The results indicates the adoption of hybrid model may reduce the complexity of modeling, especially in some intricate mechanical-electrical integration analysis.
