Abstract
CBTC (communication-based train control) is a new train control technology which aims at managing a platoon of several trains to move simultaneously on a particular train segment through precise maintenance of a predetermined inter-train safe distance. The success of the CBTC technology implementation thus relies strongly on the availability of dedicated real-time communication systems which can accommodate the continuous data/information exchange/transmission among neighboring trains. With an objective of reducing both the computational effort and the communication network loads/traffics in such a CBTC implementation, this paper proposes a Lyapunov-based event-triggered control scheduling approach which can guarantee the input-to-state stability property of the closed loop CBTC system.
