Self-triggered linear quadratic networked control

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 of H2 and H∞ performance indexes, yielding to the statement and solution of H2 and H∞ 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.
