Delft University of Technology & Philips Research Laboratories
Four Year Ph.D. Position in Robust Control
In a joint project of the TU Delft (Delft) and Philips Research
(Eindhoven) the goal is to develop methodologies for system
identification and robust control which are specially suited for
high-performance motion tracking control of consumer electronic
products. Particular attention should be paid to the integration of
model identification with an assessment of the underlying
uncertainties and the design of controllers which provide desirable
performance for all models in the identified class.
These aims should be achieved in close cooperation of two
investigators, one responsible for identification aspects (Hans
Doetsch, supervised by Dr. P.M.J. van den Hof) and one
concentrating on robust controller design (vacant position,
supervised by Dr. C.W. Scherer). The candidate is expected to
contribute in the modeling of the occurring uncertainties, the
formulation of robust control problems guaranteeing stability
and performance, the assessment of applicability or the
development of variations of existing synthesis techniques
(H-infinity, mu-synthesis, LMI-techniques, multiobjective
control), and the controller implemention on a prototype CD
player mechanism. In view of this broad range of topcis we
expect any applicant to have, in addition to a firm engineering
background, an above average knowledge of the mathematics
related to robust control.
The research should start in fall 1994 and is performed in the
Systems and Control Group at the TU Delft, headed by Prof. O.H.
Bosgra, with regular meetings with the group around Dr. M. Steinbuch
at Philips Research Eindhoven.
Please send your application including a curriculum vitae and a
description of undergraduate and graduate studies with details of
the final year project (including marks/grades) to
Dr. Carsten Scherer

NEW BOOK ANNOUNCEMENT
Title: Topics in Control Theory
Authors: H.W. Knobloch, Universitaet Wuerzburg, Germany /
A. Isidori, Universita degli Studi di Roma, Italy /
D. Flockerzi, Universitaet Wuerzburg, Germany
About the Book:
One of the key concerns in modern control theory is the design of steering
strategies. The implementation of such strategies is done by a regulator.
Presented here is a self-contained introduction to the mathematical background
of this type of regulator design. The topics selected address the matter of
greatest interest to the control community at present, namely, when the design
objective is the reduction of the influence of exogeneous disturbances upon
the output of the system.
In a first scenario the disturbance signal is regarded as a deterministic time
series with known dynamics but unknown parameters. The design objective is
then the asymptotic disturbance compensation. In a second scenario, no
information about the disturbance signal is available apart from some bounds.
Here, in an H-approach, control strategies are worked out which will prove
efficient for all such disturbances.
The intention of this book is to present ideas and methods on such a level
that the beginning graduate student will be able to follow current research.
New results are included, especially for nonlinear control systems, and as a
service to the reader, an extensive appendix presents topics from linear
algebra, invariant manifolds and calculus of variations, information which is
hardly to be found in standard textbooks.

Title: Residue Currents and Bezout Identities
Authors: C.A. Berenstein, University of Maryland, College Park, USA /
R. Gay, Universite de Bordeaux, France /
A. Vidras, A., Kyoto University, Japan /
A. Yger, Universite de Bordeaux, France
About the Book:
The objective of this monograph is to present a coherent picture of the almost
mysterious role that analytic methods and, in particular, multidimensional
residue have recently played in obtaining effective estimates for problems in
commutative algebra.
Bezout identities, i. e., f1g1 + ... + fmgm = 1, appear naturally in many
problems, for example in commutative algebra in the Nullstellensatz, and in
signal processing in the deconvolution problem. One way to solve them is by
using explicit interpolation formulas in Cn, and these depend on the theory of
multidimensional residues. The authors present this theory in detail, in a
form developed by them, and illustrate its applications to the effective
Nullstellensatz and to the Fundamental Principle for convolution equations.
The objective of this monograph is to present a coherent picture of the almost
mysterious role that analytic methods and, in particular, multidimensional
residue have recently played in obtaining effective estimates for problems in
commutative algebra.

Title: Computational Optimal Control
Editors: R. Bulirsch, TH Muenchen, Germany /
D. Kraft, Fachhochschule Muenchen, Muenchen, Germany
About the Book:
There is public agreement that all resources should be used sparingly both
from the point of view of economy and ecology. Therefore optimization is the
tool of choice in controlling industrial and economic processes.
This book collects the reviewed papers of the ninth IFAC Workshop on Control
Applications of Optimization, which took place in Munich in September 1992.
Highlights from the ensuing discussions have been incorporated by the authors.
The volume reflects the state of the art in the application of finite and
infinite dimensional optimization to open and closed loop control problems.
Its spectrum ranges from theoretical foundations of the proposed methods and
numerical implementations of algorithms to applications to real world
problems. Emphasis lies on the solution of practical industrial problems in
aerospace, mechanical and electrical engineering, manufacturing technology and
economic and management systems.
Among the theoretical papers are contributions from nonlinear programming
(interior point methods, large structured problems, nonsmooth problems, and
vector-valued criteria) and optimal control (multipoint boundary value
problems, state and control constraints, feedback solutions,
differential-algebraic systems and differential games).

It is our intention that the journal will continue as a journal of
engineering systems and the mathematics that underlies them. Its present
focus is upon electrical and mechanical engineering, especially
information and communication systems, including control theory; robotics;
wavelets; nonlinear dynamics and fractals; neural computation; signal
processing and mechanics. We realize that no description of this kinds
can be comprehensive and we therefore encourage authors to put forward new
topics for publication, provided that they fall within the broad scope of
the journal or are related to one of the current topics. Of particular
interest are emerging mathematical techniques, and especially their
applications.
The core of the journal will remain research papers. To encourage
definitive accounts of research we emphasize that there is no arbitrary
limit on the length of papers. Authors of particularly long papers, more
than 6,000 words, should consult with us beforehand; but the bibliographic
data for the journal shows that its papers are cited for many years and
this is a trend we wish to continue.
Papers are normally published within eight months of receipt and often
more quickly if major revisions are not required. In addition, we are
introducing a section of brief communications which will be published in
3-4 months provided they warrant the urgency.
We intend to publish review articles and we invite authors to put
forward proposals for such articles, to be major pieces of writing up to
10,000 words long. Review articles may either cover a relatively narrow
topic at the frontiers of research or may be broader with a strong
tutorial flavor.
Manuscripts for publication should be sent directly to the managing editor
at the Franklin Institute.

ICIAM '95
Hamburg , Germany
CALL for MINI-SYMPOSIA PROPOSALS
SIAM has been allotted 30 mini-symposia at the ICIAM meeting at
Hamburg, July 3 thru July 7, 1995. We invite you and your colleagues
to submit a proposal by July 15, 1994. THE PROPOSALS SHOULD BE SENT TO
THE SIAM OFFICE. The final decision on the mini-symposia will be made
by the the ICIAM Program Committee to insure a balanced program.
Forms for making the proposal can be obtained from SIAM
(iciam@siam.org) or from the SIAM gopher. (These forms are for the
genaral call for mini-symposia; ignore the dates and address of
return.) We welcome suggestions for other topics and organizers.
A final decision on mini-symposia will be made by Sept 15, 1994.
Here is some information and helpful comments. These suggestions are
guides but they are not inviolate.
1) In the interest of fairness, an individual should not participate
and/or organize more than one mini-symposium.
2) The organizer should be a member of SIAM but it is desirable that
the speakers be chosen to reflect the international character of the
ICIAM meeting.
3) If the organizer is a speaker then he/she should nominate another
person to chair the session.
4) No funding has been provided for the expenses of these mini-symposia.
5) The mini-symposium format allows for a variety of formats eg.
roundtable discussions, presentations of variable length, etc.
There will be a more general call for submission of mini-symposium at
a later date.
PLEASE PASS THIS NOTE ON TO COLLEAGUES WHO MAY NOT HAVE ACCESS TO THIS NETWORK.

August 29-31, 1994
Leuven - Belgium
This third workshop on Algorithms and Parallel VLSI Architectures addresses
novel research in the area of highly parallel systems, focused on algorithms,
architectures as well as design methodologies and compilation. Both custom
realisation and programmable processor realisation are included.
It is a continuation of two previous workshops of the same name which
were held in Pont-a-Mousson, France, June 1990, and Bonas, France,
June 1991.
The Workshop will be held in the Arenberg Castle of the Katholieke
Universiteit Leuven. Leuven is located in the centre of Belgium, only
30 km from Brussels and 20 km from Brussels International Airport.
