Abstract

This paper considers scalar linear systems with process noise and packet drops between the sensor and the controller. Motivated by considerations about the efficient use of resources, we design an event-triggered transmission policy to ensure exponential convergence of the second moment of the plant state to an ultimate bound in finite time. Our technical approach evaluates the satisfaction of the control objective in an online fashion and designs an event-triggering policy that is specifically tailored to it. In addition to formally establishing that the event-triggered policy meets the desired objective, we also quantify its efficiency by providing an upper bound on the fraction of expected number of transmissions over the system executions. Simulations illustrate the results.
