摘要
在四电磁铁支撑钢板磁浮系统的气隙同步协调控制中,为改善气隙动态同步性能,需要消除各单电磁铁系统增益参数、动态参数不匹配以及悬浮过程中不确定性扰动对各气隙的影响。基于钢板动力学模型,在单电磁铁悬浮控制基础上,提出一种动态同步控制策略,引入气隙、速度双重交叉耦合控制,通过选取相应同步误差以建立多电磁铁系统间的协调关系,补偿参数差异、扰动所造成的影响,减小气隙轮廓误差。在一台钢板磁浮装置上进行实验,结果验证了所提出的气隙动态同步控制的有效性。
Control aspects of gap synchronized coordination for 4-electromagnet supported steel plate magnetic suspension system were discussed.In order to improve gap dynamic synchronization performance,it was necessary to eliminate effects on gap due to gain parameter,dynamic parameter mismatch between each single magnet suspension system and uncertain disturbances while steel plate was levitated.Based on motion equations of steel plate,one dynamic synchronized control strategy was proposed by introducing both gap and velocity cross coupling control into independent levitation control.To decrease gap contour error,related synchronization error terms were selected and coordination between multi-magnet suspension system was determined to compensate for parameter difference and disturbance influence.Experiments were carried out on the prototype of steel plate magnetic levitation system and experimental results shown the effectiveness of the proposed control method.
