Abstract:
This paper studies a formation control problem
in communication-based train control (CBTC) implementation
under an event-triggered control scheduling framework using
the formalism of input-to-state stability (ISS) property. The
examined control objective that is considered in this paper is
that of guaranteeing the boundedness of the resulting intertrain
safe distance with respect to variation on some predefined
reference distance and speed profiles. Using the fundamental ISS
property of event-triggered control scheduling implementation,
this paper shows that the resulting event-triggered CBTC system
implementation can be guranteed to be ISS with respect to
the reference movement (inter trains safe distance and velocity)
profiles provided that the used event-triggered parameter satisfies
a particular inequality.
