Distributed Coordinative Control for Virtually Coupled Sky Train Set via A Novel Finite-Time Sliding Mode Control Approach
Pages 212 - 216
Abstract
Virtual coupling (VC) represents a cutting-edge railway technology that enables unit trains to operate closely together as a coordinated unit without physical connections, enhancing efficiency and capacity on railway networks. Recently, a novel rail transit method, sky trains, has been gradually developing with technological and infrastructural advancements. This paper introduces the concept of virtually coupled sky train set (VCSTS) and proposes a finite-time coordinative control method for VCSTS that addresses state constraints and uncertain parameters. First, a VCSTS train-following model that accounts for uncertain resistances and unknown disturbances is constructed. Then, by combining finite-time control and barrier function theory, a novel distributed coordinative control strategy is designed, which can realize finite-time convergence as well as manage uncertain parameters and state constraints. Using Lyapunov theory, the finite-time convergence of the designed control strategy is rigorously proved. Ultimately, simulations are performed to validate the theoretical findings.
