摘要
磁悬浮系统是复杂的强耦合系统,研究中未充分考虑轨道的弹性形变,会造成磁浮列车和轨道之间产生耦合振动的现象,而考虑这一因素对系统的影响无疑增加了研究的难度;为了便于问题的求解,采用非线性系统理论解耦的方法,对单电磁铁悬浮系统进行纵向解耦控制,并对解耦后的子系统进行极点配置使其满足要求的性能指标;仿真结果表明该方法有效地使复杂问题简单化,并且能够实现系统的全局稳定和良好的动态性能。
Electromagnetic suspension systems are complicated and strong coupling.The interaction between aerotrain and roadway may bring oscillation,however,the considered factor will add more difficulties into study.The work presented in this paper considers the influence by the distortion of roadway,and applys nonlinear system theory to the decoupling control for single electromagnetic suspension system.Then decoupling subsystem can be improved by collocating pole location.The results reveal that this method effectively simplify complexity and keep good capability of system.
