  This article studies the event-triggered control problem of general nonlinear
systems with time delay. A novel event-triggering scheme is presented with two
tunable design parameters, based on a Lyapunov functional result for the
input-to-state stability of time-delay systems. The proposed event-triggered
control algorithm guarantees the resulting closed-loop systems to be globally
asymptotically stable, uniformly bounded, and/or globally attractive for
different choices of these parameters. Sufficient conditions on the parameters
are derived to exclude Zeno behavior. Two illustrative examples are studied to
demonstrate our theoretical results.
