Cooperative control algorithm of high-speed train based on potential function theory

At present, the quasi-moving block signaling system is widely used in high-speed railway, and the quasi-moving block signaling system will be replaced by the moving block signaling system in the future. In order to solve the problem that the line transport efficiency is limited due to the lack of an effective train cooperative control algorithm under the existing traffic mode, this paper studies the cooperative control algorithm of high-speed trains in moving block mode on the basis of autopilot. A distributed controller based on bounded potential function is proposed to ensure the predetermined speed and position tracking performance of the train. Finally, combined with the parameters of CRH380A EMU, the feasibility of the multi-train cooperative control algorithm is verified in the simulation model.
