Dynamic event-triggered control: Tradeoffs between transmission intervals and performance

Event-Triggered Control for String-Stable Vehicle Platooning

“…In this paper, we consider event-triggered control (ETC) schemes that determine the transmission instants by means of a triggering condition that depends on locally available output measurements, see, e.g., [2], [7], [11], [12], [14], [33], [41], [47], [51] and the references therein for more details on ETC. In this way, the communication resources are only used when necessary to maintain desired closed-loop behavior and the utilization of communication resources is reduced.…”

“…and whereû i−1 evolves according to (10) and (11). The input-output relation of u 0 and χ 1 does not involve network-induced imperfections since the first vehicle follows a virtual reference vehicle, i.e.,û 0 (t) = u 0 (t) for all t ∈ R 0 .…”

Event-Triggered Control Systems Under Denial-of-Service Attacks

“…Let us remark that for linear systems the conditions above can be obtained systematically by solving a multi-objective linear matrix inequality (LMI) problem, see [12], [13], [26] for more details. Also several classes of nonlinear systems satisfy these conditions, see [13].…”

“…In this paper, we we follow a design philosophy based on a dynamic event-triggered control scheme [12], [13], [20]- [23], which has several advantages over their static counterparts, see [1], [12], [20], [22], [23] for more details on these advantages. A dynamic triggering condition in the context of this paper will take the form…”

“…By exploiting the Zenofreeness property of the ETC scheme presented in [12], [13], we show that for the proposed ETC scheme, such a positive minimal-inter event time (MIET) exists by design despite the presence of disturbances and/or DoS attacks. By employing the DoS characterization as presented in [5], [6], the obtained results hold for wide classes of relevant DoS attacks.…”
