Abstract
This paper deals with the stabilization of linear systems with
process noise under packet drops between the sensor and the
controller. Our aim is to ensure exponential convergence of the
second moment of the plant state to a given bound in finite
time. Motivated by considerations about the efficient use of the
available resources, we adopt an event-triggering approach to design
the transmission policy. In our design, the sensor's decision to
transmit or not the state to the controller is based on an online
evaluation of the future satisfaction of the control objective. The
resulting event-triggering policy is hence specifically tailored to
the control objective. We formally establish that the proposed
event-triggering policy meets the desired objective and quantify its
efficiency by providing an upper bound on the fraction of expected
number of transmissions in an infinite time interval. Simulations
for scalar and vector systems illustrate the results.
