Abstract
This paper addresses the problem of asymptotic
stabilization for linear time-invariant (LTI)
systems using event-triggered control under finite
data rate communication - both in the sense of
finite precision data at each transmission and
finite average data rate. Given a prescribed rate of
convergence for asymptotic stability, we introduce
an event-triggered control implementation that
opportunistically determines the transmission
instants and the finite precision data to be
transmitted at each transmission. We show that our
design exponentially stabilizes the origin while
guaranteeing a positive lower bound on the
inter-transmission times, ensuring that the number
of bits transmitted at each transmission is upper
bounded, and allowing for the possibility of
transmitting fewer bits at any given time if more
bits than prescribed were transmitted on a previous
transmission. In our technical approach, we consider
both the case of instantaneous and non-instantaneous
transmissions. Several simulations illustrate the
results.
