This reorganized, revised, and expanded edition of a two-volume set is a
self-contained account of quadratic cost optimal control for a large
class of infinite dimensional systems. The study of this problem shows
the beautiful interplay between optimality and the qualitative
properties of systems such as controllability, observability,
stabilizability, and detectability.
New material includes an expanded chapter on the control of linear
systems and a chapter on linear quadratic two-person zero-sum
differential games. A unique chapter on semigroup theory and
interpolation of linear operators brings together advanced concepts and
techniques that are usually treated independently. The material on delay
systems and structural operators is not available elsewhere in book
form.
Control of infinite dimensional systems has a wide range and growing
number of challenging applications. This book is a key reference for
anyone working on these applications, which arise from new
phenomenological studies, new technological developments, and more
stringent design requirements. It will be useful for mathematicians,
graduate students, and engineers interested in the field and in the
underlying conceptual ideas of systems and control.
