摘　　要：研究电磁永磁混合型EMS磁悬浮列车的悬浮控制问题,根据控制指标要求设计零功率控制器,内环采用次速电流环,外环采用自适应PD环,它能保证系统在全质量范同内悬浮性能保持一致。仿真及试验表明,增加自适应机制后,系统的抗干扰能力强,在质量改变时表现出稳健性。The levitation control prohlera of EMS hybrid maglev train is discussed. Following the requiremerit of the control indexes, the zero-power controller is designed. With a current loop as interior loop and an adaptive PD loop as exterior loop, the controller guarantees that the system is consistent in the full-scale of mass. The simulation and test results show, that with the adaptive mechanism, the system features high capability of antiintefference and stability during the variation of masses,
