Introduction

Abstract

This chapter provides a concise review of control performance limitation studies, together with a survey into the literature most relevant to the topics of this book. We focus in particular on the relation between information theory and control theory, and the recent developments in networked control.

There is an obvious analogy between the problem of smoothing the data to eliminate or reduce the effect of tracking errors and the problem of separating a signal from interfering noise in communications systems.
