Virtual Coupling Train Cruise Control Based on Finite Time Distributed Control

Virtual coupling is a research hotspot to improve railway transport capacity. Train cruise control is the key to realizing virtual coupling. A virtual coupling train cruise control problem based on agent theory is proposed. A leader-follower model of a virtual coupling train is established, taking into account the dynamic changes in basic resistance and random additional resistance. Information transfer between trains is achieved using wireless communication technology. Based on the finite time distributed multi-agent control theory, a novel virtual coupling train cruise controller was designed based on finite time distributed. The effect of the controller designed in this paper is verified and analyzed through the simulation comparison experiment. Compared with the existing non-finite time controllers, the results show that the proposed controller based on finite time distribution is effective, especially in control precision and convergence speed. The initial train working condition do not have any effect on the convergence rate of the finite time distributed controller.
