  Event-triggered control (ETC) and time-triggered control (TTC), the classical
concepts to determine the transmission instants for networked control systems,
each come with drawbacks: It is difficult to tune ETC such that a certain
bandwidth is respected, whereas TTC cannot adapt the sampling interval to the
current state of the control system. In this article, we provide an overview
over rollout ETC, a method aimed at reconciling the advantages of ETC and TTC.
We unite two variants of rollout ETC under a common framework and present
conditions for convergence and compliance with a predefined bandwidth limit.
Furthermore, we demonstrate that rollout ETC satisfies a performance bound and
that it allows for a very flexible transmission scheduling similar to classical
ETC. The mentioned beneficial properties are illustrated through extensive
numerical simulations.
