摘　　要：为了解决磁悬浮列车直线电机传动系统与悬浮系统相互影响的关键问题,提出了一种直线感应电机恒转差频率磁场定向控制方法,在实现牵引的同时尽可能地减小了法向力波动对悬浮系统的影响。试验结果表明该控制系统性能优良、稳定。It presents a field oriented control strategy with constant slip frequency to minimize the influence of normal force fluctuations on the suspension system during traction running, in order to tackle the key issues on the interplay between drive system and suspension system of maglev train LIM. Experimental results show that the control system is stable and has good performances.
