标题： Vertical Vibration Reduction of Maglev Vehicles using Nonlinear MPC

摘要： 这项工作提出了一种新颖的非线性模型预测控制（NMPC）策略，用于高速磁悬浮车辆，该策略明确地将机械悬挂动力学纳入控制模型中。 与传统方法不同，传统方法通常忽略悬浮磁铁与车体运动之间的相互作用，所提出的方法通过同时建模电磁力和悬挂行为，实现了预测性振动缓解。 这种综合方法通过减少由轨道不规则性引起的垂直振动，显著提高了乘客舒适度和乘坐质量。 此外，它还允许更有效地调整精确气隙跟踪与乘坐舒适度之间的权衡。 基于Transrapid的详细多体模型进行的仿真表明，该方法在振动抑制方面优于现有控制器，使其成为未来高速磁悬浮应用的有前途的解决方案。 显示英文摘要

摘要： This work presents a novel Nonlinear Model Predictive Control (NMPC) strategy for high-speed Maglev vehicles that explicitly incorporates mechanical suspension dynamics into the control model. Unlike conventional approaches, which often neglect the interaction between levitation magnet and car body motion, the proposed method enables predictive vibration mitigation by modeling both electromagnetic forces and suspension behavior. This integrated approach significantly improves passenger comfort and ride quality by reducing vertical oscillations caused by track irregularities. Moreover, it allows for a more effective tuning of the trade-off between precise air gap tracking and ride comfort. Simulations based on a detailed multibody model of the Transrapid demonstrate that the method outperforms existing controllers in vibration suppression, making it a promising solution for future high-speed Maglev applications.
