In order to enhance the safety as well as comfort of multiple high-speed trains in cooperative operation, a cooperative cruise control strategy of multiple high-speed trains based on improved distributed consensus algorithm is proposed. Firstly, the safety distance interval is designed that can change with the train speed in real time. Secondly, the distributed cooperative control strategy is given by combining weighted hyperbolic tangent function. Meanwhile, the error model of the closed-loop train dynamics is transformed into a typical second-order multi-agent system model by coordinate transformation, and the asymptotic stability of the closed-loop system under the error state is proved by using Lyapunov’ s stability theorem. Finally, the proposed method is verified by simulation, the proposed method can dynamically adjust the safety distance between trains and always keep it within [-0. 7,0. 7]m/ s 2 . The results show that the safety and comfort of multiple trains tracking operation can be guaranteed.
