This book gives a unified and unique presentation of low gain and high
gain design methodologies. In particular the development of low gain
feedback design methodology is discussed. The development of both low
and high gain feedback enhances the industrial relevance of modern
control theory, by providing solutions to a wide range of problems that
are of paramount practical importance. This detailed monograph provides
the reader with a comprehensive insight into these problems: research
results are examined and solutions to the problems are considered.
Compared to that of high gain feedback, the power and significance of
low gain feedback is not as widely recognized. The purpose of this
monograph is to present some recent developments in low gain feedback,
and its applications. Several low gain techniques are examined,
including the control of linear systems with saturating actuators,
semi-global stabilization of minimum phase input-output linearizable
systems and H2 suboptimal control.
