Abstract :
This paper deals with Networked Control Systems (NCS) design, under the constraint of limited bandwidth on the communication channel. A linear quadratic regulator 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. Examples are presented to illustrate the validity of the theory.
