A finite-time event-triggered model control strategy is proposed for multi-train high-speed train systems (MHSTs) with switching topologies. Due to the complexity of the high-speed railway operation environment, the communication topology of MHSTs is time-varying and changes between a set of directed graphs. This paper studies the distributed cooperative leader following consistent control of MHSTs and introduces a new event-triggering strategy to determine the execution time of information exchange and control updates between adjacent trains. First, a control protocol for MHSTs finite time is designed to transform the leader following consistency problem into a system calming problem, and then, an event triggering algorithm is proposed. Finally, the effectiveness of the proposed finite-time event triggering method in the cooperative cruise control of multiple high-speed train systems is verified by numerical calculations.

Keywords: Multi-train high-speed train systems (MHSTs); switching topology; event-triggered; finite-time; collaborative consistency
