In order to simulate the motion process of the levitation system of high-speed maglev trains and analyze the system response under different conditions, it is necessary to establish a levitation system model and conduct controller design and simulation analysis. Firstly, the basic structure and working principle of the levitation system of high-speed maglev trains with the joint structure as the basis unit were introduced. The mathematical model of the levitation system under ideal conditions was derived through a mechanism analysis method. Then, the levitation system model was simplified reasonably, and a nominal controller was designed for the simplified model. Finally, the control effect of the nominal controller was verified through simulation, and the levitating and landing processes of the permanent magnet and electromagnetic hybrid levitation system under simulation and experimental conditions were compared. The results show that the variation of physical quantities such as levitation gap and levitation current obtained from the simulation coincides with the trend of the actual system, with an error of less than 5% during static levitation.
