“…Various disturbances and uncertainties are considered, such as the time delay of the braking system 3,4 , the additional resistance 5 , and the external resistances 6 . Compared with subway trains, the train operating environment and braking system of high-speed strains have higher complexity and uncertainty 7,8 . As high-speed trains run at higher speeds, the braking process has greater inertia, and the operating environment is more open and variable, so the impact of the disturbances is more obvious.…”

This paper aims to realize precise stop control of high-speed trains with the air-electric combined characteristics under complex scenarios, including external disturbances and the time delay of the braking system. To describe the train braking process, a dynamic model and a braking system model which refine the air and electric braking methods as well as their three working modes are established. For better control performance, multiple disturbances and uncertainties during the actual stopping process of high-speed trains are analyzed and accurately modeled. Then, applying the principle of terminal sliding mode control, meanwhile, combining with parameter adaptive and fuzzy control methods, the refined adaptive terminal sliding mode controller (RATSMC) is designed. The simulation results show that the stopping precision of RATSMC is 0.14m, which is improved by 71%, and the passenger comfort is improved by 68% compared with the classic terminal sliding mode controller (TSMC).

With the gradual maturity of the automatic train operation (ATO) system in subways, its application scope has also expanded to the high-speed railway field. Considering that the ATO system is still in the early stages of operation, it will take time to fully mature, and definite specifications of the requirements for system operation have not yet been formed. This paper presents the operational design domain (ODD) of the high-speed railway ATO system and proposes a scenario analysis method based on the operational design domain to obtain the input conditions of the system requirements. The article models and verifies the scenario of the linkage control of the door and platform door based on the UPPAAL tools and extracts the input and expected output of the system requirements of the vehicle ATO system. Combined with the input conditions of the system requirements, the system requirements of the vehicle ATO in this scenario are finally obtained, which provides a reference for future functional specification generation and test case generation.
