Message of the Coordinator

Let me first wish you the very best for 2015 and I hope it will bring us yet another productive year for our network !

I use the opportunity to remind you about the upcoming Benelux Meeting in Systems and Control which will be held from March 24 to 26, 2015 in Lommel : the deadline for abstract submissions is January 14th ! You can find more about it here. I also want to draw your attention to the graduate school courses of 2015 and in particular to the Francqui lectures that will be given in Louvain-la-Neuve in February-March by our colleague Rodolphe Sepulchre. You will find more about it below. I hope many of you will participate in these events.

Best wishes to all of you.

Stability, Control, and Computation for Time-Delay Systems: An Eigenvalue-Based Approach, Second Edition by Wim Michiels and Silviu-Iulian Niculescu

SIAM Publications, 2014, xxiv + 435 pages, ISBN 978-1-611973-62-4

Keywords: Delay, eigenvalue analysis, nonlinear eigenvalue problems, control, computational mathematics, dynamical systems.

This second edition replaces Stability and Stabilization of Time-Delay Systems: An Eigenvalue-Based Approach (DC12, ISBN: 978-0-898716-32-0), which is no longer available.

Time delays are important components of many systems in, for instance, engineering, physics, economics, and the life sciences, because the transfer of material, energy, and information is usually not instantaneous. Time delays may appear as computation and communication lags, they model transport phenomena and heredity, and they arise as feedback delays in control loops. This monograph addresses the problem of stability analysis, stabilization, and robust fixed-order control of dynamical systems subject to delays, including both retarded- and neutral-type systems. Within the eigenvalue-based framework, an overall solution is given to the stability analysis, stabilization, and robust control design problem, using both analytical methods and numerical algorithms and applicable to a broad class of linear time-delay systems.

In this revised edition, the authors :

  • make the leap from stabilization to the design of robust and optimal controllers and from retarded-type to neutral-type delay systems, thus enlarging the scope of the book within control;
  • include new, state-of-the-art material on numerical methods and algorithms to broaden the book’s focus and to reach additional research communities, in particular numerical linear algebra and numerical optimization; and
  • increase the number and range of applications to better illustrate the effectiveness and generality of their approach.

Audience

Engineers, researchers, and graduate students in control and systems engineering, as well as computational and applied mathematicians, will find this book of great interest. It will also be of value to undergraduate and graduate students and laboratory researchers.
