中文摘要
      针对传统自适应控制器暂态性能较差的问题, 本文设计了一种基于确定性模型的高速列车二阶段自适应控制器, 实现了对给定参考曲线的渐进跟踪. 首先, 通过受力分析建立了列车的纵向动力学模型, 并根据先验知识确定列车模型中未知参数的区域范围, 从而在未知参数的区域范围内建立列车的确定性辨识模型集; 然后, 采用凸组合的思想设计控制器,并利用二阶段自适应控制策略更新控制器参数; 最后, 以CRH380AL型高速列车在济南–徐州段的数据进行仿真实验, 仿真结果表明该控制系统具有理想的稳定和渐进跟踪特性, 并且能够快速逼近列车模型参数突变后新的工作点, 显著地改善了列车速度跟踪控制系统的暂态性能.
英文摘要
      For the poor transient response of traditional adaptive controller, a second level adaptive controller with fixed models is designed to realize the asymptotic tracking of a given reference curve. Firstly, a longitudinal model of the train is established by force analysis. Then, according to the prior knowledge, the unknown parameter space of the train model is determined and a fixed identification model set of the train can be established within the unknown parameter space. The convex combination method is used to design the controller, and the second level adaptive control strategy is used to update the controller parameters. Finally, the simulation experiment is carried out with the data of CRH380AL type high-speed train processing in Jinan to Xuzhou Section. The simulation results show that the system has desired stability and tracking performance, and can quickly approach the new working point after a dynamic mutation of train model parameters, significantly improving the transient performance of the speed tracking control system.
