摘　　要：EMS型磁浮列车高速运行时由于车轨相互耦合,使悬浮系统的动力学行为变得复杂,影响车辆安全性、舒适性。为提高系统的鲁棒性,提出了一种基于逆系统理论的非线性悬浮控制器设计方法。首先,建立了EMS型磁浮列车的单磁铁非线性动力学模型。然后,讨论了基于逆系统的非线性反馈控制方法在悬浮控制器设计中的运用,通过系统伪线性化及系统综合,设计出了基于逆系统反馈线性化和鲁棒伺服控制的组合控制器。数值仿真验证了逆系统控制方法的有效性。When the EMS maglev train is running at high speed, the dynamic behavior of the suspension system becomes more complex due to the coupling of the vehicle tracks, which influences the safety and comfort of the vehicle. In order to improve the robustness of the system, a design method of nonlinear suspension controller based on the inverse system theory is proposed. Firstly, a nonlinear dynamic model of a single magnet of the EMS maglev train is built. Secondly, the nonlinear system feedback control method based on inverse system is discussed in the design of the suspension controller, through the pseudo linear system and the system integration, a composite controller based on inverse system feedback linearization and the robust servo control is designed. Numerical simulation verifies the effectiveness of the inverse system control method.
