摘要
为研究磁浮车辆悬浮控制器的状态观测器参数对悬浮稳定性的影响,解决磁浮车辆悬浮不稳的问题,建立单电磁铁与柔性轨道梁的耦合模型。通过对悬浮系统传递函数的研究,得到速度激励信号频率与悬浮系统对轨道梁的功率输出的关系曲线,并得到状态观测器参数对系统性能的影响规律。由此得出结论,通过绘制"悬浮系统对轨道梁的振动能量输出功率"与"轨道梁主频率"间的关系曲线,即可得到不考虑轨道梁阻尼时,悬浮系统可适应轨道的临界参数。
In order to solve problems of suspension instability of maglev vehicles, a coupling model of single-electromagnets and flexible track-beams was established to study on how parameters of state observers of suspension controllers affect the suspension stability of maglev vehicles. Researches about the transfer function of suspension systems were conducted and gotten some impressive results, such as curves that plot the relationship between the frequency of speed excitation signals and the power output of the suspension system to track-beams, influence rules that parameters of state observers affect system performance of maglev vehicles and so on. Based on the study about the change rule of state-space model of the coupling system, a conclusion is drawn that it is possible to analysis critical parameters of track-beams, which suspension system can be adapted to.
