EMS型磁浮列车悬浮控制系统对爬坡能力的约束分析

The Analysis of Levitation Control System's Restriction on the Grade Ability of EMS Maglev

分析EMS型磁浮列车的悬浮控制系统对爬坡能力的约束。首先基于系统开环传递函数和通用的悬浮控制器模型,通过将其单实极点配置为闭环非主导极点,将爬坡能力与控制系统的频带和阻尼等参数对应起来;然后以圆曲线型缓和曲线为例,分析得出坡道段的最大跟踪误差与行车速度的关系;最后结合允许误差,给出最小竖曲线与最大爬坡速度半径的关系。研究结果对实际工程具有一定的指导意义。

The problem of levitation control system＇s restriction on the grade ability of EMS Maglev is analyzed. Firstly, based on the transform functions of the system and controller models, the relation between the grade climbing ability and frequency band and damp are corresponded by regulating the single-real pole to non-dominant pole. Secondly, the relation between the maximum tracking error and the moving velocity is analyzed based on the example of the circular transition curve. Finally, comparing the tolerable error, the relation between the minimum curve radius and the maximum climbing velocity is tabled at the end , which is significant to engineering.
