Every physical actuator is subject to saturation. When the actuator saturates the performance
of the control system designed will seriously deteriorate. Currently there is a surge of
interest in increasing the practical applicability of control theory by incorporating the
effect of saturation into the design of a control system. Control Systems with Actuator
Saturation: Analysis and Design examines the problem of actuator saturation in depth. The
overall approach takes into account the saturation nonlinearities at the outset of the control
design. In the case that a control law is designed a priori to meet either the performance or
stability requirement it analyzes the closed-loop system under actuator saturation
systematically and redesigns the controller in such a way that the preformance is retained
while stability is improved. It also presents some related results on systems with state
saturation or sensor saturation. Features and topics: * Results apply to general open-loop
systems including exponentially unstable ones. Thus they are widely applicable to practical
systems * Problems such as controllability stabilizability transience performance distribute
rejection and output regulation are treated in a systematic manner. * Analytic description of
the null controllable region is first obtained. Various feedback laws are designed that work on
the entire null controllable region or an arbitrarily large portion of it. * Analysis tools are
developed for performance assessment of existing control systems under actuator saturation. *
Examples are worked out in detail to demonstrate the usefulness of the results. This book is an
excellent resource for professionals researchers practitioners and graduate students in
control electrical and mechanical engineering. All scientists and engineers interested in
control systems with actuator saturation will find this book an essential resource. Some
first--year graduate courses in linear systems and multivariable control or some background in
nonlinear control systems would greatly facilitate the reading of this book.
