超导磁浮车的μ鲁棒控制研究

Research on μ robust control of superconducting maglev vehicles

用μ控制方法对超导磁浮车二次悬挂系统进行了鲁棒控制策略的研究,并对控制器进行了综合和系统的仿真。仿真结果表明,μ控制能有效地抑制车体共振点附近的振动,在参数存在摄动的情况下,μ控制比H∞控制具有更好的性能鲁棒性。

The robust control strategy for active suspension of superconducting maglev vehicle is studied, the robust controller is synthesized and the digital simulation is accomplished using μ control approach in this paper. The results of simulation show that the vehicle body's vibration near resonance point is restrained effectively by μ control, and μ control has better performance robustness than H∞ control.
