为了降低轨道随机不平顺对高速磁浮列车导向系统的影响,研究了轨道随机不平顺影响下的导向控制器设计方法。在介绍导向系统结构的基础上,推导了导向系统的数学模型;基于该模型,分析了轨道随机不平顺对导向系统的影响。采用成熟的最优控制理论,通过将轨道随机不平顺引入控制器的性能指标,给出了考虑轨道随机不平顺的导向控制器设计方法。通过仿真表明,这种控制器减小了轨道随机不平顺对导向系统的影响,取得了期望的控制性能。
In order to reduce the influence of track irregularity on the guidance system of high-speed maglev train, the design of the guidance controller under the random irregularity of track is studied. Based on the introduction of the structure of the guidance system, the mathematical model of the guidance system is deduced. Based on the model, the influence of random orbit on the guidance system is analyzed. Based on the matured optimal control theory, the design of the guidance controller considering the random stochastic track is given by introducing the random track irregularity into the performance index of the controller. Simulation results show that the controller can reduce the influence of track irregularities on the guidance system and achieve the desired control performance.
