**First, some personal thoughts on
publishing:** I
think we (as a research community) publish way too much.
Everyone is
always busy trying to meet a paper submission deadline or reviewing
other people's papers. I wish we had more time to think about our ideas,
discuss them with colleagues, and select and develop the best ones.
If we produce fewer papers, their quality will be
higher and it will be easier for others to keep up with them now and
find them in the future, which
will mean higher long-term value and impact of our work. I am
certainly guilty
of writing
too many papers myself, even
though I
actually write
fewer papers than many of my colleagues. The current academic
system unfortunately
puts pressure on all of us to publish more than we should, and so we
need to (gradually) change the system.
We should
resist "bean counting" when it comes to hiring and promotions, and
keep ourselves and our students focused on depth and quality. In fact,
even in the current system - at least at top institutions - it is more
beneficial
for one's career to publish
a
few really good papers than a lot of mediocre ones, but not everyone seems to realize it.

CALCULUS OF VARIATIONS AND OPTIMAL CONTROL THEORY:
A CONCISE INTRODUCTION, Princeton University
Press, 2012. ISBN 978-0-691-15187-8. Online preview (HTML) | Free preliminary copy (PDF) | Sample quotes | Front and back cover | Courses that use the book This is a textbook for a first-year graduate course on calculus of variations and optimal control theory. Its aim is to provide a concise and rigorous introduction to the subject without requiring extensive background in control theory or advanced mathematics from the student. After presenting the main results in calculus of variations, the book makes a gradual transition to optimal control and discusses the maximum principle, the Hamilton-Jacobi-Bellman theory of dynamic programming, and linear-quadratic optimal control. Unique features of the book include: - Logical and notational consistency in the exposition of classical and modern topics provides a unified view of the field
- A complete proof of the maximum principle is the centerpiece of the book, with special attention paid to preparing the ground for this proof beforehand
- Remarks tracing the historical evolution of ideas and results complement the technical developments
From reviewers’ comments: “The manuscript is a very scholarly – and indeed concise – introduction to optimal control theory. While many books on the topic have been published, the author argues convincingly in the preface for the utility of his contribution, which is marked by a nice balance of rigor and accessibility, an elegant historical progression, and a careful and complete proof of the maximum principle. Without doubt, the author has achieved the objectives stated in the preface. A course based on this manuscript should be a pleasure to take, an enriching experience guided by careful mathematics, fascinating historical perspectives, and thought-provoking exercises… The notes and references at the end of each chapter are excellent, as is the flow of the chapters.” “I can not think of another text which can serve as a brief introduction to the field, which explains the maximum principle well, and which is accessible to graduate students in engineering… The author put a lot of effort into explaining most of the technical material, clearly with the students in mind. The organization of the material is good, so is the choice of presented topics. The size of the manuscript is very manageable… The exercises appear challenging but well-chosen and should greatly help students understand the material.” |

SWITCHING
IN SYSTEMS AND CONTROL, Birkhauser, Boston, MA, Jun 2003.
Volume in series Systems and Control: Foundations and Applications.
ISBN 978-0-8176-4297-6.
Available through SpringerLink here (subscription required). This book examines switched systems from a control-theoretic perspective, focusing on stability analysis and control synthesis of systems that combine continuous dynamics with switching events. The theory of such switched systems is related to the study of hybrid systems, which has recently attracted considerable attention among control theorists, computer scientists, and practicing engineers. Aimed at readers with a background in systems and control, this book bridges the gap between classical mathematical control theory and the interdisciplinary field of hybrid systems. The book is divided into three main parts: - Part I introduces the classes of systems studied in the book
- Part II develops stability theory for switched systems; it covers single and multiple Lyapunov function analysis methods, Lie-algebraic stability criteria, stability under limited-rate switching, and switched systems with various types of useful special structures
- Part III is devoted to switching control design; it describes several wide classes of continuous-time control systems for which the logic-based switching paradigm emerges naturally as a control design tool. Switching control algorithms for several specific problems are discussed.
Requiring only familiarity with the basic theory of linear systems, the book is suitable as a text for a graduate course on switched systems and switching control. It may also serve as an introduction to this active area of research for control theorists and mathematicians, as well as a useful reference for experts in the field. |
