The last thirty years have witnessed an enormous e?ort in the ?eld of
robust control of dynamical systems. The main objective of this book is
that of presenting, inauni?edframework,
themainresultsappearedintheliterature on this topic, with particular
reference to the robust stability problem for linear systems subject to
time-varying uncertainties. Thebookmainly focuseson thoseproblems for
which ade?nitive solution has been found; indeed most of the results we
shall present are given in the form of necessary and su?cient conditions
involving the feasibility of Linear Matrix Inequalities based problems.
For self-containedness purposes, most of the results provided in the
book areproven.Wehavetriedtomaintainthedevelopmentoftheproofsassimple as
possible, without sacri?cing the mathematical rigor. Some parts of the
book (especially those contained in Chaps. 2, 3 and 5) can be teached in
advanced control courses; however this work is mainly devoted to both
researchers in the ?eld of systems and control theory and engineers
working in industries which want to apply the methodologies p-
