Abstract
As the latest research direction of train-to-train communication, virtual coupling train formation technology has attracted the attention of many scholars. This paper studies the influence of time delay on the formation of virtual coupled trains. We proposed a distributed PID controller, which means that trains can still form a stable fleet operation under the influence of communication delay and control delay. After modelling and analysis, the research uses Matlab to conduct simulation, involving two sets of experiments. Factors including speed, acceleration, position, position error, expected distance between adjacent trains and actual distance between adjacent trains are simulated. The results demonstrate that the distributed PID controller can effectively control the impact of time delay on the virtual coupling fleet.

The virtual coupling train formation technology, as the latest research direction of train-to-train communication, has attracted the attention of many scholars. This paper investigates the influence of time delay on the formation of virtual coupled trains.
We propose a distributed PID controller that allows trains to maintain stable fleet operation despite communication and control delays. After modeling and analysis, this study uses Matlab for simulations, involving two sets of experiments. Factors such as speed, acceleration, position, position error, expected distance between adjacent trains, and actual distance between adjacent trains are simulated. The results indicate that the distributed PID controller can effectively manage the impact of time delay on the virtual coupling fleet.
