LMI Control Toolbox
---------------------
We are pleased to announce the mid-June release of the
LMI Control Toolbox for use with MATLAB. This toolbox
is an easy gateway to the fast-growing field of LMI
optimization and LMI-based control. It contains:
* a user-friendly environment to specify and solve
general LMI optimization problems (the LMI Lab)
* a collection of specialized tools for the analysis
and design of control systems via LMI techniques.
The LMI Lab is the core feature of the LMI Control Toolbox.
It is flexible, fully programmable, and provides
specialized solvers for the three generic LMI optimization
problems. Thanks to a GUI called the LMI Editor, LMI
constraints can be specified directly as symbolic matrix
expressions with structured matrix variables. For instance,
a Lyapunov inequality is entered as A'*X+X*A+Q < 0 after
declaring X as a symmetric matrix variables. The LMI Lab
uses a structured representation of such LMIs where only
A and Q are stored. This structure-aware approach minimizes
storage requirements and boosts the efficiency of the LMI
solvers.
The control-oriented tools cover state-of-the-art applications
of LMI techniques to robust control. These include tools for
* robust stability/performance analysis, using either
mu-analysis, quadratic stability, parameter-dependent
Lyapunov functions, or the Popov criterion
* multi-model/multi-objective state-feedback synthesis
with a combination of LQG and H-infinity performance
and regional pole placement constraints
* Riccati- and LMI-based H-infinity synthesis (with
automatic regularization of singular problems in
Riccati-based synthesis)
* multi-objective output-feedback synthesis (mixed
H2/Hinf synthesis with regional pole placement)
* loop shaping design (including a GUI to specify the
shaping filters)
* design of robust gain-scheduled controllers for linear
parameter-varying systems.
The user's manual is complete with an introduction to LMIs,
details on the LMI formulation of the various control
applications, numerous examples, and four demos.
The LMI Control Toolbox will be on display at the MATLAB booth
at the '95 ACC.

Topic: Exterior Differential Systems, Nonholonomy, and Nonlinear Control
New tools and techniques from nonlinear geometric control theory and
exterior differential system are needed to further research the control of
nonholonomic and nonlinear systems. Some specific research topics include
(1) developing obstacle-avoidance path planning algorithms and interactive
steering simulations to test out these algorithm; (2) stabilizing the system
around the resulting trajectories and finding actual implementations that
work well; (3) generating trajectories for systems with drift; (4) employing
exterior differential systems techniques to develop nonlinear normal forms
for use in control theory; (5) investigating how to convert to these normal
forms by using feedback transformations and how to control systems in these
normal forms. Various applications include the control of locomotion systems
such as wheeled robotic vehicles, aircraft, swimming robots, and snake-like
robots.

Feedback Control Problems Using MATLAB and The Control System Toolbox
Dean K. Frederick and Joe H. Chow
Bookware Companion Problems Book
PWS Publishing Company
ISBN 0-534-93798-5
Excerpts from Preface
The purpose of this book is to reinforce the learning process for those
who are studying the introductory aspects of control systems engineering
by allowing them to use a digital computer to rapidly work a wide range
of numerical problems. The book is built around illustrative examples
that demonstrate the steps involved in the analysis and design process.
The examples are followed by a variety of problems that consist of
follow-up "what-if?" problems, textbook-type reinforcement problems,
open-ended exploratory problems, and realistic comprehensive problems.
To accomplish this objective, the book uses the power of MATLAB and the
Control System Toolbox. This book and the accompanying software diskette
will be a valuable supplement to any of the numerous textbooks that
cover the introductory aspects of feedback control.
The problems in this book are suitable for students taking a senior-level
course on the analysis and design of continuous-time feedback control
systems. In addition to classical control design methods based on
transfer-function models, the book also covers state-space models and
design methods. The material is organized like many of the introductory
control system textbooks. The state-space modeling of systems is
introduced early to emphasize its importance in modeling real-world
problems. However, for those following a syllabus without any state-space
modeling content, this material can be skipped without any loss of
continuity.
The book is also suitable as a refresher for students entering a graduate
control system program. In addition, practicing engineers who already
have the necessary control background can use the book to learn about
MATLAB in a familiar context, and to learn about the Control System
Toolbox for the computer-aided design of classical control systems at a
level more advanced than the tutorial found in the Control System Toolbox
user's manual.

This textbook is essentially self-contained; the basic prerequisites are
advanced calculus, elementary ordinary differential equations, and linear
algebra. The book constitutes an outgrowth of the authors' instructional
material that has been developed over a 5-year period from a course in
statistical control systems design which the first author has taught at
the University of Houston, and a period of 10 years from courses in
stochastic control systems which the second author taught at Pennsylvania
State University and Texas A&M University. Over the years of teaching,
we have begun to feel a need and an urge to develop a textbook that fits
the instructional demands and diversity of our own students, and is
accessible to general audience. Our students have come from mixed
backgrounds and their interests vary from engineering to physics, applied
mathematics, economics and operations research. They are generally second
year graduate or higher, who have taken advanced calculus and have been
exposed to some elementary statistics and deterministic control theory.
As instructors, we have tried to provide guidance for students on how best
to study stochastic control systems in a modern context, supplying detailed
derivations and rigorous proofs, and assisting them in developing a coherent
mathematical theory. It is these endeavors and our firm commitment to
providing students with a strong mathematical foundation that have resulted
in this modest textbook, which we hope can serve for the same purpose in
graduate schools and related discipline areas. A guided plan for using this
book is provided at the beginning of the text. While mathematical rigor and
coherence were our main concerns in the writing of the book, the real driving
force is our desire to convey those aspects of modern stochastic control
theory that have actually been put to use in practical engineering
applications. Every chapter contains many examples and exercises.

>>>>>>>>>> Wiley's back cover: <<<<<<<<<<
An introduction to the new design for nonlinear control
systems -- BACKSTEPPING -- written by its own architects.
This innovative book breaks new ground in nonlinear and adaptive
control design for systems with uncertainties. Introducing the
recursive backstepping methodology, it shows -- for the first
time -- how uncertain systems with severe nonlinearities can be
successfully controlled with this new powerful design tool.
Communicative and accessible at a level not usually present in
research texts, "Nonlinear and Adaptive Control Design" can be
used as either a stand-alone or a supplemental text in courses on
nonlinear or adaptive control, as well as in control research and
applications. It eases the reader into the subject matter, assum-
ing only standard undergraduate knowledge of control theory, and
provides a pedagogical presentation of the material, most of
which is completely new and not available in other textbooks.
Written by the creators of backstepping, the book:
* Introduces the basic design tools and demonstrates their effec-
tiveness through worked examples
* Provides detailed proofs and application examples (active
suspension, jet engine, induction motor, ...)
* Develops adaptive backstepping, tuning functions, and modular
designs with full state feedback
* Generalizes the methodology to systems with output feedback
* Describes the advantages of the new adaptive nonlinear tech-
niques over traditional methods
* Offers a systematic methodology for performance improvement
* Provides new designs for linear systems which can be used in-
dependently from the rest of the book
* Is self-contained with an extensive summary of stability and
passivity prerequisites
* Includes sixty illustrations and tables with design algorithms

Abstract:
This thesis addresses the non-linear system identification problem,
and in particular, investigates the use of neural networks in system
identification. An overview of different possible model structures is
given in a common framework. A nonlinear structure is described as the
concatenation of a map from the observed data to the regressor, and a
map from the regressor to the output space. This divides the model
structure selection problem into two problems with lower complexity:
that of choosing the regressor and that of choosing the non-linear map.
The possible choices for the regressors consists of past inputs and
outputs, and filtered versions of them. The dynamics of the model
depends on the choice of regressor, and families of different model
structures are suggested based on analogies to linear black-box
models. State-space models are also described within this common
framework by a special choice of regressor. It is shown that
state-space models which have no parameters in the state update
function can be viewed as an input-output model preceded by a
pre-filter. A parameterized state update function, on the other hand,
can be seen as a data driven regressor selector. The second step of
the non-linear identification is the mapping from the regressor to the
output space. It is often advantageous to try some intermediate
mappings between the linear and the general non-linear mapping. Such
non-linear black-box mappings are discussed and motivated by
considering different noise assumptions.
The validation of a linear model should contain a test for
non-linearities and it is shown that, in general, it is easy to detect
non-linearities. This implies that it is not worth spending too much
energy searching for optimal non-linear validation methods for a
specific problem. Instead the validation method should be chosen so
that it is easy to apply. Two such methods, based on polynomials and
neural nets, are suggested. Further, two validation methods, the
correlation-test and the parametric F-test, are investigated. It is
shown that under certain conditions these methods coincide.
Parameter estimates are usually based on criterion minimization. In
connection with neural nets it has been noted that it is not always
optimal to try to find the absolute minimum point of the criterion.
Instead a better estimate can be obtained if the numerical search for
the minimum is prematurely stopped. A formal connection between this
stopped search and regularization is given. It is shown that the
numerical minimization of the criterion can be view as a
regularization term which is gradually turned to zero. This closely
connects to, and explains, what is called overtraining in the neural
net literature.

CALL FOR PAPERS
A Special Issue of Mechanical Systems & Signal Processing
devoted to Rotating Machinery
Rotating machinery represents perhaps the most important class of mechanical
systems. The demands on this class of systems in recent years have increased
at a significantly greater rate than the development and use of the advanced
signal processing methodologies needed to accommodate them. The goal of this
special issue is to provide a focussed forum for the discussion of the
limit- ations of traditional signal processing tools and for presentation of
advanced tools particularly appropriate for intra-cycle analysis of rotating
machinery. The first, should focus on the limitations of signal processing
methods that assume that signals are wide sense stationary random processes
and that systems are time-invariant. For example, while these assumptions
may be valid in certain settings, they are seldom verified prior to applying
signal and system analysis tools which rely on them. Furthermore, in the
case where signal records are collected synchronously with a top-dead-center
pulse, it is almost certain that the underlying random processes are not
wide sense stationary. The second type of paper should focus on advanced
signal and system identification tools which relax the above
assumptions. These might include methods for time-varying or time-periodic
random processes and systems.
Both types of papers should address the validity of the underlying
assumptions pertaining to the tools to be studied, at least in part within
the context of experimental measurements obtained from rotating machinery.
Papers prepared following the MSSP Journal's Instructions to Authors should
be submitted to:

ARO-NASA Montana State University Workshop on Intelligent Control:
Hybrid and Exterior Differential Systems
July 24 - July 29 1995
Bozeman, Montana
This workshop focuses on intelligent control. It is a continuation of a set
of workshops sponsored jointly by ARO and NASA; the first was at MIT in
October 1993, the second at Cornell in October 1994.
This year, the focus is on two apparently disparate topics: hybrid control
and exterior differential systems. The first topic is an area of great
current interest featuring the use of new formal techniques for the analysis
of systems which have a mixture of continuous and discrete event parts.
These techniques are frequently used in the control of complex,
hierarchically-organized control systems. The use of exterior differential
systems is a new way of unifying path planning and control for complex
systems at the lowest or "regulation" layers.
This workshop will feature the use of methods from exterior differential
systems, differential geometry, game theory, automata for the control of
complex, hierarchical control systems, nonholonomic systems, systems
with substantial nonlinearity in their dynamics and systems on Lie groups.
A partial list of topics to be covered include: linearization by state
feedback, nonholonomic systems, variational problems and exterior
differential systems, nonlinear normal forms and rolling, splines on Lie
groups, linearization by dynamic state feedback, path planning using
generalized splines, nonlinear maneuvering: connections with flat systems.
We invite researchers and students to both participate and speak at the
workshop. Some travel and other support will be available.
The following is a partial list of people who have committed to speak thus
far:
Andrzej Banaszuk (Ga Tech), Robert Bryant (Duke), Linda Bushnell (ARO),
Peter Caines (McGill), Robert Gardner (UNC), John Hauser (Colorado),
Robert Hermann (Boston U), L.R. Hunt (Dallas), Lucas Hsu (Princeton),
Naomi Leonard (Princeton), Petar Kokotovic (UC Santa Barbara),
Jerry Marsden (Caltech), Clyde Martin (Texas Tech), George Meyer (NASA Ames),
Richard Montgomery (Santa Cruz), Richard Murray (Caltech),
Brad Paden (UC Santa Cruz), Shankar Sastry (UC Berkeley),
William Shadwick (Toronto), Willem Sluis (Caltech), Dawn Tilbury (U
Michigan), and Z. Zhang (Texas Tech).
The program committee is: Linda Bushnell, Jagdish Chandra (ARO),

International Conference on
COMMUNICATIONS, COMPUTING, CONTROL and
SIGNAL PROCESSING
to honor the contributions of Professor Thomas Kailath
June 22-26, 1995
Stanford University, Stanford, CA, USA
The traditional systems disciplines of communications, computation, control
and signal processing are becoming increasingly important in addressing
major technological challenges of the coming century, in fields such as
materials processing, highway automation, and ubiquitous personal
communications, among many others. Moreover the boundaries between these
separate disciplines are rapidly being blurred by the many demands of these
applications. This conference will highlight several of these recent trends
and results, presented by leading scientists and engineers from around the
world.
Invited speakers include: N. Abramson, B. Anderson, K. Astrom, B. Atal,
A. Bruckstein, S. Boyd, J. Cioffi, T. Cover, B. De Moor, P. Dewilde,
T. Durrani, C. Foias, D. Forney, R. Gallager, M. Gevers, I. Gohberg,
