摘要:设计了基于全状态反馈的考虑轨道板振动的柔性磁悬浮控制算法，并与传统的不考虑轨道板振动的刚性控制算法进行比较。分析了轨道板刚度对磁悬浮系统稳定性的影响，探究了存在轨道基础激励时不同控制算法下的磁悬浮系统响应。结果表明：不考虑轨道板振动的刚性控制器对轨道板刚度的要求很高，并且对轨道基础激励敏感，极易造成振荡和失稳；考虑轨道板振动的柔性控制算法对轨道板刚度要求低，在基础激励作用下稳定性仍旧能够满足要求。



Abstract:In this paper, a flexible levitation control method for maglev vehicle-guideway system is proposed based on full-state feedback theory and is compared with traditional stiff control method. The relationship between track stiffness and maglev system stability is investigated. Then, the responses of the system under different irregularity excitations are tested. Results show that the traditional stiff control method without considering the movement of track requires high track stiffness. The system is very sensitive to irregularity,which results in oscillation and instability. However, the flexible control method with considering the movement of track has relatively low requirement for track stiffness and can be stable under different irregularity inputs.
