以中低速磁浮列车悬浮控制器主电路为研究对象，建立了充电回路和斩波器电路的数学模型。利用dSPACE实时仿真软件和硬件平台建立了悬浮控制器主电路仿真模型，并对充电回路和斩波器电路以及电流跟随情况进行了仿真验证和对比分析。仿真和测试结果表明，建立的悬浮控制器主电路仿真模型较为准确，为后续用仿真模型替代真实的悬浮控制器主电路提供了理论依据，为悬浮控制策略的开发与调试奠定了基础。

The main circuit of the suspension controller for low and medium speed maglev trains is studied and a mathematical model of the charging circuit and chopper circuit is developed. A simulation model of the suspension controller main circuit is established using the dSPACE real-time simulation software and hardware platformand the charging circuit and chopper circuit as well as the current tracking situation are verified and compared. The simulation results show that the simulation model of the suspension controller main circuit established is more accurate. A theoretical basis is provided for the subsequent replacement of the real suspension controller main circuit by the simulation modeland the foundation is also provided for the development and debugging of the suspension control strategy.
