电磁永磁混合磁悬浮系统自适应控制方法研究

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围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.

Research on Adaptive Control Method of Hybrid Maglev System

The levitation control problem of EMS hybrid maglev train is discussed.Following the require- ment 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 antiinterference and stability during the variation of masses.
