  This paper presents a class of event-triggering rules for dynamical control
systems with guaranteed positive minimum inter-event time (MIET). We first
propose an event-based function design with guaranteed control performance
under a clock-like variable for general nonlinear systems, and later specify
them to general linear systems. Compared to the existing static and dynamic
triggering mechanisms, the proposed triggering rules hold the robust global
event-separation property, and can be easily implemented on practical digital
platform. Namely, it is shown that the minimum inter-event time can be flexibly
adapted to the various hardware limitations. Finally, several numerical
simulations are given to illustrate the theoretical results.
