当同时考虑诸如阻力摩擦力和空气动力阻力、车辆之间的相互作用以及列车系统固有的非线性牵引/制动缺口等不可避免的因素时，高速列车的位置和速度跟踪控制问题变得有趣但具有挑战性。在本文中，推导了具有反映电阻和瞬态影响的单坐标动态模型的多点质量，并基于此，在牵引/制动非线性和饱和限制下提出了计算成本低廉的鲁棒自适应控制设计，该设计具有速度和位置跟踪的最佳任务分配。结果表明，该方法不仅对外部扰动、气动阻力、机械阻力和瞬态冲击具有鲁棒性，而且还能适应未知的系统参数。数值模拟也证实了所提出方法的有效性。
The problem of the position and velocity tracking control of high-speed trains becomes interesting yet challenging when simultaneously considering inevitable factors such as the resistive friction and aerodynamic drag forces, the interactive impacts among the vehicles, and the nonlinear traction/braking notches inherent in train systems. In this paper, a multiple point mass with a single-coordinate dynamic model that reflects resistive and transient impacts is derived, and based on this, computationally inexpensive robust adaptive control designs with optimal task distribution for speed and position tracking are proposed under traction/braking nonlinearities and saturation limitations. It is shown that the proposed method is not only robust to external disturbances, aerodynamic resistance, mechanical resistance, and transient impacts but adaptive to unknown system parameters as well. The effectiveness of the proposed approach is also confirmed through numerical simulations.
