摘　　要：城市轨道交通列车制动过程面临着速度波动、坡度变化、载荷变化等多种复杂扰动因素,必须做到精准控制。文章基于多刚体动力学理论建立列车纵向动力学模型,构建模块化的制动力模型,界定列车制动过程中的主要扰动因素,然后,设计自抗扰控制器,通过跟踪微分器、扩张状态观测器和非线性状态反馈等模块,准确估计扰动信息并实施扰动补偿。在此基础上,综合考虑速度约束条件和安全域概念,研究终点停车保护、超速保护和滑脱保护等安全防护控制策略。The braking process of urban rail transit trains is faced with a variety of complex disturbance factors such as speed fluctuations,slope changes,and load changes,which must be accurately controlled.Based on the multi-rigid body dynamics theory,the longitudinal dynamics model of the train is established,the modular braking force model is constructed,the main disturbance factors in the braking process of the train are defined,and then the active disturbance rejection controller is designed,and the disturbance information is accurately estimated and the disturbance compensation is implemented through the tracking differential,the extended state observer and the nonlinear state feedback modules.On this basis,considering the speed constraints and the concept of safety domain,the safety protection control strategies such as stop protection,overspeed protection and slippage protection are studied.
