摘　　要：轨道交通列车的防滑控制性能过差会影响列车的制动性能和稳定性能,为了提高轨道交通列车的安全性,以分段制动的方式控制轨道交通列车的滑动状态,提出快速轨道交通列车分段制动防滑控制仿真方法。通过分析轮轨间粘着力和滑移变化曲线建立轨道交通列车的纵向运行学模型,并以上述模型为基础,将轨道交通列车的整体制动过程分割成多组制动区段,通过将单位制动区段与滑模控制器结合,实现轨道交通列车的分段制动防滑控制。仿真结果表明,无论是在轨道粘着条件始终维持在较低水平的工况条件下,还是在轨道粘着条件发生突变的工况条件下,所提方法控制下的实际行驶速度均与目标行驶速度吻合,验证了上述方法具有较好的控制效果。At present,the ability of anti-skid control for rail transit trains is affecting the braking performance and stability of the train.In order to improve the safety of rail transit trains and control their sliding state by sectional braking,this paper proposed a method of simulating anti-skid control of rapid rail transit trains in a sectional braking way.At first,a longitudinal kinematic model of the rail transit train was built after analyzing the change curve of the adhesion force and drift between wheel and rail.Based on the model,the braking process of the train was divided into several groups of braking sections.Finally,the braking sections were combined with the sliding mode controller to realize the anti-skid control for rail transit trains.Simulation results show that the actual speed controlled by the proposed method is consistent with the expected driving speed whether the rail adhesion condition is always kept at a low level or the adhesion condition changes suddenly.Therefore,the method has a good control effect.
