This issue celebrates the 10th Anniversary of the E-letter on Systems,
Control, and Signal Processing. Issue number 1 was published Sept. 2, 1986.
The original subscriber list consisted of 78 recipients, whose names are
listed below. Since then, the list has grown to well over 3000 subscriptions,
and the E-letter has spawn a number of similar activities, such as the
E-letter on digital signal processing and others. The founders and original
editors were Brad Dickinson from Princeton and Eduardo Sontag from Rutgers.
Since issue 58, published in May 1993, the editors have been Anton Stoorvogel
and Siep Weiland from Eindhoven.
In these times of popular interest in the Web, with electronic mailing lists
and discussion groups probably in the tens of thousands, it is perhaps ironic
to point out that even the benefits of simple e-mail were not widely
acknowledged ten years ago. When we polled people regarding the idea of
setting up an electronic newsletter, the reactions were, to put it mildly, not
uniformly encouraging. In fact, when we attempted to first post the original
call for contributions and subscriptions, on a bulletin board at the SIAM
Conference on Linear Algebra in Signals, Systems, and Control, in Boston,
August 1985, the SIAM staff at first objected, not appreciating the point of
such electronic communication. (Eventually, not only was the posting allowed,
but the SIAM Activity Group on Systems and Control decided to co-sponsor the
E-letter as an official activity. The IEEE Control Systems Society also
became a sponsor in due time.)
The first issue included the preliminary program for the 1986 Digital Signal
Processing Workshop, the TOC for the Sept 1986 IEEE Trans on Information
Theory, and announcements of preprints by Antoulas, Anderson, Spong, and
Sontag. The original list of subscribers was as follows:
Jan Allebach, Thanos Antoulas, J.D.Aplevich, John Baras, Bill Baumann, Toby
Berger, Gilmer Blankenship, Charles Boncelet, Steve Boyd, Roger Brockett, Sid
Burrus, Peter Caines, Peter Cappello, John Chiasson, Jim Clark, Costas
Courcoubetis, Ed Coyle, George Cybenko, Christopher DeMarco, Dave Delchamps,

Paul Fuhrmann, Y. Genin, Claude Gomez, David Goodman, Bob Gray, Michiel
Hazewinkel, Chris Heegard, Bill Hopkins, Anil Jain, Y.C. Jenq, Don Johnson,
Tom Kailath, Jim Kaiser, R.E. Kalman, Mos Kaveh, P. Krishnaprasad, P.R. Kumar,
Gerardo Lafferriere, Victor Lawrence, Edward Lee, Bede Liu, Steve Marcus,
Bengt Martensson, Bob McEliece, Nader Mehravari, Dave Messerschmidt, George
Meyer, Rodolfo Milito, Bud Mishra, Martin Morf, Rick Perry, H. Vince Poor,

Schwartz, Eduardo Sontag, Mark W. Spong, Ken Steiglitz, Hector Sussmann, Stew
Tewksberry, John Thomas, David Thomson, Tran Thong, Sergio Verdu, Wing Wong,
Aaron Wyner, Stan Zak.
We feel that, even at a time of Web sophisticated search engines and a
profusion of online information on journals and conferences, there will always
be a place for edited electronic newsletters, which summarize relevant and
targeted information in a timely fashion. Our thanks to Anton and Siep for a
great job, and see you again at the guest editorial for the 20th Anniversary!

SIGNALS AND SYSTEMS DEMONSTRATIONS
Demonstrations of basic concepts in signals and systems are now available on
the World Wide Web at URL
http://www.ece.jhu.edu:80/class/214/demos/index.html
Students in a basic signals and systems course can be assigned to run
demonstrations on particular topics as part of their homework. Also the Web
demos and/or the downloadable Matlab M-files can be used for interactive
lecture demonstrations in a suitably equipped classroom.
These demonstrations are under development in a project directed by Wilson
J. Rugh, ECE Department, Johns Hopkins University, to explore the use of the
Web in engineering education. The first four demonstrations, briefly
described below, focus on fundamentals of Fourier analysis and properties of
systems. They have been tested on PC's, and they are known to run on some
other platforms.
LISTEN TO FOURIER SERIES
Sound is used to introduce basic notions of Fourier series, including
harmonic content and filtering. To run this demonstration you should have
at least the equivalent of a 386 PC with a sound card and ~.wav file player.
(Prepared by Kevin Rosenbaum.)
HARMONIC PHASORS
This demonstration uses rotating vectors in the complex plane (phasors) to
illustrate basic characteristics of Fourier series, including convergence
properties, Gibbs effect, and windowing. It is based on ideas from the 1971
movie Harmonic Phasors II by William H. Huggins at Johns Hopkins. To run
this demonstration you should have at least the equivalent of a 486 PC with
an ~.mpeg file player. Included is a downloadable M-file for execution on
Matlab. This permits interactive exploration of additional examples and
user-created Fourier series. To run the M-file you will need at least the
Student Edition of Matlab. (Prepared by Nabeel Azar.)
MAGNITUDE AND PHASE SPECTRA
Basic properties of the frequency spectrum of a signal are presented,
including the effect of various operations in the time domain and in the
frequency domain. In particular there is a downloadable M-file for
execution on PC-Matlab. This permits further, interactive exploration of
frequency characteristics of signals using a "spreadsheet" format. To run
the M-file you will need at least the Student Edition of Matlab, PC
version. (Prepared by Christopher Hocker.)
SYSTEM PROPERTIES
This demonstration invites the user to apply test input signals to a
selected, unknown system - either continuous time or discrete time - in
order to determine whether the system is linear, time invariant, causal,
stable, and memoryless. A color monitor is recommneded. (Prepared by Raman
Venkataramani.)
FINE PRINT: Please note that these are beta versions of the demonstrations,
and they are offered without warranty. You may find a few features that are
under construction. Comments and suggestions are welcome by e-mail to
rugh@jhu.edu.

From data acquisition to identification, control design and implementation
in 1 coherent software package : WinPIM+TR
In order to implement a high-performance control system, it is necessary to
know the dynamic characteristics of the plant. System Identification is a
rapid and cost effective way for obtaining the dynamic model of the plant
without the need for a complex mathematical analysis of the physical laws
governing the process. WinPIM+TR allows to identify a process during its
normal operation by using very small test signals in order to acquire the
experimental data. A PC is connected to the process to be observed, through
a standard input/output board (with A/D and D/A converters) among a list of
about 10 commercially available boards from several manufacturers.
A large choice of identification methods is available in the software which
provides user with assistance for the selection of the appropriate method
for identifying a good model for any type of industrial process. Finding
the order of the model to be identified and its pure time-delay does not
require anymore a trial and error approach. WinPIM is the first software
available worldwide that allows to estimate the process model order and
time-delay directly from the input/output experimental data. It also
provides a confidence level on the results. Statistical tests allow to
validate the resulting model (they are much more revealing than simple
visual superposition of the plant and model outputs).
WinPIM+TR software also provides a controller design tool which, starting
from a plant model and the desired closed-loop performances in tracking and
regulation, computes the parameters of a PID or of an "R-S-T" digital
controller. The R-S-T digital controller allows to handle independently the
disturbance rejection (regulation) and the desired tracking. It can also
handle systems with time-delay or with complex dynamic characteristics.
A particular emphasis is given on the robustness of the resulting control
system with respect to changes in the process dynamics. This is
accomplished through the use of the new synthesis method CPPSS (Combined
Pole Placement / Sensitivity Shaping), which exploits the robustness margin
indexes and the shape of the sensitivity functions. Robust PID are designed
with the KLV tuning rules.
Nice graphs obtained from simulation are not enough : it is important to
test on the real plant (or process) the control algorithms which you have
obtained with our design tools. This is quickly and easily done with the
WinPIM+TR software. The process will be driven by the same I/O board used
for data acquisition. The control / regulation algorithm obtained is
provided in C source code. It is easily portable to other platforms, among
which digital control system, programmable controller, micro-controller
board, stand-alone controller, ... (it only requires additions,
multiplications and shift registers). Applications using a wide variety of
computer hardware have been succesfully carried out in industry.
This software is already used by more than 200 customers, including :
Aerospatiale, Mc Donnell Douglas, Kaiser Aluminium, Air Liquide, Renault,
C.E.A., Solvay, Peugeot, Digital Equipment, Electricite De France, Kodak
Pathe, Michelin, Thomson Optronique, M.I.T., University of California,
Singapore National University, Chalmers University, James Cook University,
SUPELEC, ...
System requirements : PC (or compatible) 386, 486 or more
Windows 3.1 (or higher)
memory : 2 MB
hard disk : 4 MB
I/O board (updated list upon request)
Note : WinPIM+TR is 100% Matlab compatible.

A Ph.D. research assistantship, sponsored by ONR, is available immediately
in the Dept. of Electrical and Computer Engineering at the University of
Miami (Coral Gables, FL) in the general area of adaptive/active optical
sensing for underwater applications. The student should be a US citizen
with high academic standing, and some experience in one or more of the
following related areas:
1) Computer vision and/or image processing
2) Remote Sensing
3) Optics (e.g., Physics majors)
4) Underwater Robotics
5) Signal Processing
Though there is some flexibility in the exact topic of dissertation, the
general problem involves the development of theory-based active (adaptive)
optical sensing techniques for underwater applications. It includes
developing, based on mathematical models of imaging and medium
properties, and the scene information that is extracted by on-line
computer processing of images (about a target, medium condition, etc.),
intelligent strategies to be employed during subsequent image acquisition
to improve data quality and information content. As an example,
appropriate adjustments to, e.g., lighting. viewing position, etc., may be
made automatically in order to obtain more useful information about the
target/scene that is viwed. These images are continuously processed in
order to obtain the necessary information about the scene that would
be useful in the successful completion of a task by an autonomous agent
(robotic vehicle), or in an operator-assisted operation.
This problem, commonly referred to active or purposive vision, has
received extensive attention in computer vision in recent years, and is
particularly important in the underwater domain because of the adverse
conditions imposed by the medium physical properties.
Students with serious interest should send c.v. to Professor Shahriar
Negahdaripour via either Email (shahriar@ece.miami.edu) or mail (Dept. of
Elect. & Comp. Eng., Univ. of Miami, Coral Gables, FL 33124-0640).

New Control Titles from Birkhauser
ROBUST NONLINEAR CONTROL DESIGN
State-Space and Lyapunov Techniques
R.A. Freeman, Northwestern University & P.V. Kokotovic, University of
California, Santa Barbara
This book presents recent advances in the theory and design of robust
nonlinear control systems. In the first part of the book, the authors
provide a unified framework for state space and Lyapunov techniques by
combining concepts from set valued analysis, Lyapunov stability theory, and
game theory. Within this unified framework, the authors then develop a
variety of new control design methods suitable for systems described by
low-order nonlinear ordinary differential equations. This book emphasizes
global controller designs, that is designs for the entire region of model
validity. Because linear theory deals well with local system behavior
(except for critical cases in which Jacobian linearization fails), the
authors focus on achieving robustness and performance for large deviations
from a given operation condition.
The purpose of the book is to summarize new Lyapunov design techniques for
nonlinear systems and to raise important issues concerning large-signal
robustness and performance. The authors have been the first to address some
of these issues, and they report their findings in this text. For example,
they identify two potential sources of excessive control effort in Lyapunov
design techniques and show how such effort can be greatly reduced.
The researcher who wishes to enter the field of robust nonlinear control
might use this book as a source of new research topics. For those already
active in the field, the book can serve as a reference to a recent body of
significant work. Finally, the design engineer faced with a nonlinear
control problem will benefit from the new techniques presented here.

Systems and Control: Foundations & Applications
ADAPTIVE SYSTEMS
An Introduction
I. Mareels, Australian National University & J.W. Polderman, University of
Twente
Adaptive Systems: An Introduction presents a part of the theory of adaptive
(control) systems that is well established in the literature. The authors'
aim is to introduce the reader to adaptive systems in a rigorous but
elementary fashion. They emphasize the main stream developments in adaptive
control and signal processing of linear discrete time systems. A unified
and novel framework is developed whereby the reader can analyze and
understand (almost) any adaptive system in the literature. The so called
equilibrium analysis enables the reader to understand the limitations and
potential of adaptive systems in a transparent fashion. The behavioral
approach to linear systems theory plays an essential role at some key points
in the development. The related material, which is not yet standard
knowledge, is provided in a separate chapter.
A particularly novel feature is the presentation in some detail of so
called universal controllers. This development clearly indicates the
limitations and scope of adaptive controllers, hence its inclusion in the
book. The adaptive system synthesis problem is tackled via averaging
methods. The averaging analysis technique is introduced in its most
elementary format, specifically geared towards adaptive systems.
Every chapter is complemented by exercises that aim to develop certain
aspects of the theory as well as to give the reader a better understanding
of the actual behavior of adaptive systems. The primary aim of the book
is to teach the student about this behavior and to guide the reader
through the learning process.
Complementary to the book the authors maintain a homepage through the
publisher, http://www.birkhauser.com/books/isbn/0-8176-3877-6. The reader
is encouraged to consult this homepage to find additional exercises,
program codes for simulation and the like, or to leave his or her comments.

Systems and Control: Foundations & Applications
SAMPLING IN DIGITAL SIGNAL PROCESSING AND CONTROL
A. Feuer, Technion, Haifa & G.C. Goodwin, The University of New Castle
This book deals with signal sampling techniques in digital signal
processing and control. Particular emphasis is placed on the concept of
intersample behavior. Tools are presented for analyzing systems that
contain both sampled and continuous time signals. These topics are at the
forefront of current mathematical and engineering research and are of great
importance in practical applications. The first half of the book deals
with digital signal processing and presents a unified description of the
frequency domain characteristics of sampled and continuous signals, as well
as sampling and reconstruction of signals, lattice and Kalman filtering and
various related estimation issues. The second half of the book deals with
digital control and covers such topics as sampled data control, multirate
control and periodic systems.
Many features of the book make it ideal for both the practicing engineer
and the student. It provides tools for dealing with mixed sampled and
continuous signals. It contains a complete discussion of modern discrete
time control and a unified treatment of Fourier analysis of signals. It
covers filter design in continuous and discrete time and multi-rate signal
processing and control. It is not only the most current reference source
on sampling and its applications in digital signal processing and control
but an ideal text for a graduate level course in sampled systems.

Systems and Control: Foundations & Applications
ELLIPSOIDAL CALCULUS FOR ESTIMATION AND CONTROL
A. Kurzhanski, Moscow State University & I. V=E1lyi, Hungarian National
Bank, Budapest
The investigation of control and estimation problems under unknown but
bounded errors and disturbances, as well as those of differential games and
related issues, may lead to solutions and procedures formulated in terms of
sets and set-valued functions. However the relevant mathematical tools are
usually complicated and not easy to apply, even in the linear-convex case.
This book gives an account of an ellipsoidal calculus and ellipsoidal
techniques, developed by the authors, that allows presentation of the
set-valued solutions to these problems in terms of approximating
ellipsoidal-valued functions. Such an attack leads to effective
computation schemes and opens the way to applications and implementations
with computer animation, particularly in decision support systems.
The problems treated here are those that involve calculation of
attainability domains, of control synthesis under bounded controls, state
constraints and unknown input disturbances, as well as those of "viability"
and of the "bounding approach" to state estimation.
The text ranges from a specially developed theory of exact set-valued
solutions to the description of ellipsoidal calculus, related
ellipsoidal-based methods and examples worked out with computer graphics.
The calculus given here may also be interpreted as a generalized technique
of the "interval analysis" type with an impact on scientific computation.

Special Issue of Systems and Control Letters
on Learning Theory
Expected publication date: December 1997
Submission deadline: December 20, 1996
Guest editors: P. Bartlett and M. Vidyasagar
Learning theory is a recent subject at the intersection of a
number of disciplines, including theoretical computer science,
probability theory and statistics, artificial intelligence,
pattern recognition, and information theory. It addresses the
problem of formulating mathematical theories of how machines
`learn' and `generalize.' There are statistical and
computational components of this quantitative investigation
of machine learning. The main statistical question concerns
the relationship between the amount of data and the accuracy
of prediction or estimation. The computational side
emphasizes the design and analysis of efficient algorithms
for learning problems. Identification theory is a well-
established branch of system theory that investigates the
problem of estimating accurate models of dynamic systems.
Recently some experts in identification theory have suggested
that the learning theory paradigm may offer a new and useful
approach to the system identification problem. This
connection offers the prospects of efficient identification
procedures for general nonlinear models, finite data analysis
of identification schemes, and hence the development of
effective model order selection procedures.
We solicit papers on learning theory and its connections to
systems theory for a special issue of Systems and Control
Letters. This special issue aims to introduce results and
techniques from learning theory to the systems community,
and to provide a forum for recent research that spans both
learning theory and systems theory. Suitable topics include
(but are not limited to) the application of learning theory
to the areas of system identification, model selection methods,
and adaptive control. Manuscripts must be limited to 14 pages.
Note that Systems and Control Letters publishes concise research
papers rather than long technical notes. Please send six copies
of your manuscript by December 20, 1996 to

International Workshop on Hybrid and Real-Time Systems
(HART'97)
March 26-28, 1997
Grenoble, France
During the last couple of years, the interest in hybrid (discrete
continuous) models for modern control systems has been steadily
growing. These are systems in which physical devices interact with
controllers which incorporate discrete as well as classical
components.
Research on hybrid systems tries to meet the challenges of such
complex systems by offering various formal models that employ
continuous and discrete components such as timed and hybrid automata,
piecewise-linear dynamical systems, etc., and by investigating the
application of classical control and computer science notions and
techniques (e.g., modelling, stability analysis, verification, control
synthesis, simulation) to these models.
The hybrid nature of the models encourages the use of diverse
mathematical tools originating from both computer science (e.g., logic
and theorem proving, automata and graph algorithms) and more
traditional mathematics and engineering (dynamical systems, control
theory, linear algebra, symbolic computation). Such techniques should
be present in future tools for automating some of the activities
associated with the design of hybrid systems.
The three-day workshop will combine invited talks and presentations of
accepted submissions. Submissions are invited in all areas pertaining
to the formal verification and control of embedded systems. Topics
include, but are not limited to, formal models and specification
languages, algorithmic and deductive verification, control and
optimization, simulation and testing, design and synthesis, complexity
and decidability issues, automatic and interactive tools, experimental
results and applications.
The contributed papers will be divided into two categories:
1) Regular (category A) papers will be judged according to the
following criteria: Theoretical papers are expected to present
original and meaningful results. More practical papers should present
the application of a sound methodology or a tool to a non-trivial
case-study.
2) Short papers (category B) could be either a position paper or a
survey of one's own research on hybrid systems, as well as tool
description.
The program committee can transfer a paper from one category to
another.
Submission:
Authors are requested to submit a postscript file (or five copies) of
an extended abstract not exceeding 10 pages (for category A) or 5
pages (for category B). The abstract should start with a title page
containing the title of the paper, each author's name and affiliation,
the contact author's physical and e-mail addresses, and a one- or
two-paragraph summary. An ASCII version of the title page should
be sent separately by e-mail. The selected submissions will be published
in time for distribution at the workshop as a volume of the Springer-
Verlag Lecture Notes in Computer Science series.
