摘要：为研究电磁永磁混合悬浮的反馈控制策略，基于TR08磁浮列车参数，建立了电磁永磁混合悬浮气隙控制系统数学模型，引入了状态反馈控制策略，分析比较了混合悬浮控制系统在斜坡及阶跃启动条件时的启动性能。研究了在悬浮气隙阶跃干扰及悬浮力正弦干扰条件下，混合悬浮控制系统的调节过程。研究结果表明：混合悬浮较之常规电磁悬浮方式，具有降低电磁极功耗，增加悬浮气隙调节范围的特点；电磁永磁混合悬浮气隙控制系统具有控制精度高、响应速度快及鲁棒性能较强等优点。

Abstract: In order to study the feedback control strategy of hybrid magnetic levitation by electro and permanent magnet, based on the parameters of TR08 maglev train, a mathematic model of air gap control system with hybrid magnetic suspension was established, the control strategy of state feedback was introduced, and the startup characteristics of hybrid maglev control system were analyzed and compared under the condition of ramp and instantaneous spring inputs. With the disturbances of air gap spring and sine electromagnetic suspension force, the regulating process of hybrid maglev was investigated. In comparison to traditional electromagnetic suspension, the research results show that hybrid maglev has traits of low power losses in electromagnetic poles, longer adjusted distance of air gap, and the air gap control system of hybrid maglev has the merits of higher control precision, swifter response and stronger robust performance.
Key words: maglev train; hybrid maglev; state feedback; control strategy
