中文摘要：

一个新奇磁悬浮火车交通系统为大旅行范围被建议极端精确运动。系统由一个悬浮分系统和一个推进分系统组成。在沿着 guideway 驾驶动人的站台的推进分系统期间，悬浮分系统使用六个电磁石稳定地在 guideway 上推迟动人的站台。悬浮系统的模型，是联合系统的典型非线性的多输入多产量并且有许多内部非线性的联合特征，被推出。为证明模型，悬浮机制被 proportional-integral-differential (PID ) 第一控制控制，然后很多输入产量数据为模型参数鉴定被收集。最少平方的参数鉴定方法被使用。鉴定结果证明模型为真实系统可行、合适。

英文摘要：

A novel maglev transportation system was proposed for large travel range ultra precision motion. The system consists of a levitation subsystem and a propulsion subsystem. During the propulsion subsystem driving the moving platform along the guideway, the levitation subsystem uses six pairs of electromagnets to steadily suspend the moving platform over the guideway. The model of the levitation system, which is a typical nonlinear multi-input multi-output coupling system and has many inner nonlinear coupling characteristics, was deduced. For testifying the model, the levitation mechanism was firstly controlled by proportional- integral-differential （PID） control, and then a lot of input-output data were collected for model parameter identification. The least-square parameter identification method was used. The identification results prove that the model is feasible and suitable for the real system.
