SUMMARY This paper deals with networked control systems design, under the constraint of limited bandwidth on the communication channel. A linear quadratic problem for a fixed sampling period is solved, and this result is used for the development ofH 2andH ∞performance indexes, yielding to the statement and solution ofH 2andH ∞optimal control problems. Finally, a self‐triggered controller is designed with a switched system approach in order to improve performance. Several examples are presented in order to illustrate the validity of the developed theory. Copyright © 2013 John Wiley & Sons, Ltd.
