Abstract

We say that an event-triggered control policy is consistent if it achieves a better closed-loop performance than that of traditional periodic control for the same average transmission rate and does not generate transmissions in the absence of disturbances. In this paper, we propose a class of dynamic event-triggered control strategies that satisfy these two conditions for any linear system when performance is measured by an average quadratic cost. A numerical example shows that these conditions may not be necessarily satisfied by a well-known event-triggered policy for which transmissions are triggered if the Euclidean norm of the error between the system's state and a state prediction exceeds a given threshold.
