摘要: 为了消除磁浮列车的轨道共振,必须设计鲁棒性较强的悬浮控制系统.将悬浮控制 系统分解为电流环和悬浮子控制系统两个串行、解耦的子系统来考虑,并应用H∞控制理论 设计了电流环控制器,用时域法设计了悬浮子系统的控制器,给出了所设计的控制器在一个 单转向架磁浮列车上的悬浮试验结果.Abstract: To eliminate guideway resonance vibration in an EMS maglev vehicle system, a robust levitation controller should be designed. This paper divides a maglev control system into two serial-connected de-coupled sub-systems :current loop subsystem and levitation subsystem. H∞ control theory is applied to the design of current loop controller while the time-domain method is applied to the design of the levitation controller. Testing results of the designed controllers for a whole size single bogie EMS maglev vehicle is given.
