COURSE ANNOUNCEMENT
Practical Methods for Robust Control
by Eric Feron, Steven Hall,
Professors of Aeronautics and Astronautics, MIT
and Ragu Balakrishnan
Professor of Electrical Engineering, Purdue University
July 17-21, 1995
M.I.T. Summer Professional Program 16.30s
Tuition: $1,500
CEUs: 3.0
Robustness is the most essential quality of a properly designed control
system. Thus, it is not surprising that so much research effort has been
spent over the past five decades into examining ways to analyze robust
stability and performance of uncertain control systems. Initiated during
World War II in Russia, this research has culminated in the past decade with
the derivation of closed-form solutions to the so-called Hinfinity problem
and the advent of powerful computational tools to handle robustness
problems. Today, the large number of results available in robust control
theory makes it hard for the user to choose among many possible
methodologies the one which is going to fit his/her needs best.
The main goal of this course is to help the user understand a very large
number of robust control methodologies in a unified way. Effort will be
spent at giving an objective comparison of various stability and performance
criteria. In particular, the artificial separation between frequency-domain
and time-domain approaches to robustness analysis will be eliminated, and
seemingly different notions such as quadratic stability, Popov's criterion,
mu-analysis will be seen as particular instances of a single concept
involving Linear Matrix Inequalitiess (LMIs). Objective comparison of
various stability criteria will be performed, through a study between the
different possible trade-off between accuracy and required computational
load.
We will investigate those methods which have had the most spectacular
practical applications in spacecraft control engineering. We will present an
overview of the currently existing software tools for robust control system
analysis and synthesis, and we will spend time studying the recently
developed interior-point algorithms for solving convex programs.
Control engineers working in Aerospace, Electrical and Process Engineering
as well as many other relevant fields will find this course a precious
complement to classical, multivariable linear control theory. Numerous
practical examples based on the instructors' experience will illustrate the
practical value of the matreial presented in this course.

NEW BOOK ANNOUNCEMENT:
MODEL PREDICTIVE CONTROL IN THE PROCESS INDUSTRY
------------------------------------------------
AUTHORS: Eduardo F. Camacho and Carlos Bordons
PUBLISHER: Springer-Verlag
ISBN: 3-540-19924-1
Model Predictive Control has developed considerably in the last few years,
within both the research control community and industry. The reason for this
success can be attributed to the fact that Model Predictive Control is
perhaps the most general way of posing the process control problem in the
time domain. Model Predictive Control formulation integrates optimal
control, stochastic control, control of processes with dead time,
multivariable control and future references when available. Another
advantage of Model Predictive Control is that because of the finite control
horizon used, constraints, and in general non-linear processes, which are
frequently found in industry, can be handled.
MODEL PREDICTIVE CONTROL IN THE PROCESS INDUSTRY seeks to fill the gap
between the empirical way in which practitioners tend to use control
algorithms and the powerful but sometimes abstractly formulated techniques
developed by the control researchers. The book focuses on implementation
issues for Model Predictive Controllers and intends to present easy ways of
implementing them in industry. The book also aims to serve as a guideline of
how to implement Model Predictive Control and as a motivation for doing so
by showing that using such a powerful control technique does not require
complex control algorithms.
CONTENTS:
1. Introduction to Model Based Predictive Control
2. Model Based Predictive Controllers
3. Simple Implementation of GPC for Industrial Processes
4. Robustness Analysis in Precomputed GPC
5. Multivariable GPC
6. Constrained MPC
7. Robust MPC
8. Applications

Springer Verlag (Fax: +44-483-415-151, Phone: +44-483-418-422).

A new book
Title: Theory of Sensitivity in Dynamic Systems,
an introduction (xviii + 600 pp.)
Author: Mansour Eslami
Publisher: Springer - Verlag, Heidelberg, Germany
ISBN 3-540-54761-4 / 0-387-54761-4
The primary purpose of this book is to provide a guided entry to the
emerging field of sensitivity and robustness theory in dynamical systems
modeled with state-space representations. It is intended that both research
students and practicing engineers in general areas of control system theory
use the book as a textbook or as a reference book. In preparing this book
some basic background in linear systems and linear optimal control theory as
well as intermediate-level mathematics is assumed.
On the overall objectives of this book: It is intended to provide a broad
scope of sensitivity theory as developed in the last several decades
pertaining to electrical engineering. In this regard, preserving the past
is one of the main features of this project. The given list of classified
references, and Appendix B which in effect is a sensitivity tree, shows
where most topics are, and this feature is particularly useful for new
researchers who may not have followed the overall development of this theory
and may need a broad view of these issues before they launch their research
activities in this area. Indeed this service provides an opportunity for
new researchers to review thoroughly the earlier work. It is also hoped
that a clear and coherent research media in this very broad area is
introduced.
On the technical aspects of the book: It is intended to provide a trajectory
which covers most essential features of sensitivity theory as described in
the book. It is the opinion of this author that sensitivity in its most
generic sense is synonymous with the notion of distance. For instance, the
"distance" between the desired behavior and an actual situation represents
sensitivity. The more sophisticated and the more abstract the desired and
actual situations become, the more sophisticated and the more abstract
mathematics are needed to measure and/or to compensate this distance. The
book is prepared with the intention to direct the readers towards the
advanced aspects of this theory.

NEW BOOK ANNOUNCEMENT
Title: Digital Control: A State-Space Approach
McGraw-Hill Series in Electrical and Computer Engineering
McGraw-Hill, 1995
ISBN 0-07-066781-0
Author: Richard J. Vaccaro, Department of Electrical Engineering,
University of Rhode Island, U.S.A.
From the Preface:
This book is intended as the text for a senior-level course on the analysis
and design of digital control systems. It is assumed that the reader has
had a first course in control theory.
This book shows how linear algebra and state-space system theory are used to
design digital control systems. In addition, classical frequency-domain
tools such as Bode and Nyquist plots are used to analyze digital control
systems designed by state-space techniques.
A collection of MATLAB functions called the STATE-SPACE DIGITAL CONTROL
TOOLBOX is available. The functions implement all of the design and
analysis tools covered in this book, and programs are included to simulate
continuous-time systems under digital control. The Toolbox is available
from The MathWorks anonymous ftp server at ftp.mathworks.com in
pub/books/vaccaro/. The Toolbox comes with two demonstration scripts that
illustrate most of the toolbox functions. The scripts show the design,
analysis, and simulation for (1) control of an inverted pendulum on a cart,
and (2) multivariable digital flight control of an aircraft.
OUTLINE OF THE BOOK
Chapter 1 provides an introduction and motivation for the book.
Chapter 2 presents the linear algebra and matrix theory needed for
the rest of the book.
Chapter 3 describes state-space and transfer function models for
continuous-time and discrete-time systems. In addition, state-space
and transfer function models for several example systems are derived.
Chapter 4 shows that when a linear, continuous-time plant is operating under
digital control, it is possible to replace the continuous-time model of the
plant by a discrete-time model that describes the behavior of the plant
exactly at sampling instants. This chapter also shows how to obtain exact
discrete-time models for plants with time delay at the input.
Chapter 5 presents tools for frequency-domain analysis -- Bode plots and
Nyquist plots for discrete-time systems -- and discusses stability and
gain/phase margins. These tools are used to assess the robustness of
control systems designed in later chapters. The topic of steady-state error
and system type is also covered.
Chapter 6 shows how to design regulators using digital state feedback.
Normalized Bessel polynomials are introduced as a simple way to choose
closed-loop pole locations to achieve a desired speed of response for the
closed-loop system. The robustness of the system is assessed by looking at
a Nyquist plot of the loop transfer function. The relationship between
state feedback and PID control is presented.
Chapter 7 considers the design of observers to estimate the value of the
state vector of the plant from measurements of its input and output. Both
full and reduced-order observers are presented. We show how to design
observers that recover much if not all of the stability margins of the
state- feedback regulator.
Chapter 8 shows how to introduce a reference input into a regulator
structure to obtain a tracking system. A complete algorithm to design
tracking systems that are robust with respect to persistent disturbances and
model inaccuracies is given. The tracking systems in this chapter are
designed using full state feedback as well as observers.
Chapter 9 considers multivariable regulation and tracking systems.
This chapter presents an algorithm that finds the matrix
of feedback gains that optimizes a robustness criterion. This chapter
also includes the multivariable version of the tracking algorithm
from Chapter 8.
Chapter 10 is an introduction to optimal control. The linear quadratic
regulator for multivariable systems is derived. Only the steady-state
(infinite horizon) case is considered, and so the solution to the optimal
regulation problem is constant state feedback.
For possible course adoption, an examination copy of the book can be
obtained from your local McGraw-Hill representative.

OPTIMAL SAMPLED-DATA CONTROL SYSTEMS

(from the Preface)
Many techniques are available for designing linear multivariable analog
controllers: pole placement using observer-based controllers, loopshaping,
the inverse Nyquist array method, convex optimization in controller
parameter space, and so on. One class of techniques is to specify a
performance function and then optimize it, and one such performance function
is the norm of the closed-loop transfer matrix, suitably weighted. The two
most popular norms to optimize are the H2 and H-infinity norms. The fact
that most new industrial controllers are digital provides strong motivation
for adapting or extending these design techniques to digital control
systems.
This book is intended as a graduate text in linear sampled-data (SD) control
systems. The subject of SD control is a subdomain of digital control; it
deals with sampled signals and their discrete-time processing, but not with
quantization effects nor with issues of real-time software. SD control
systems consist of continuous-time plants to be controlled, discrete-time
controllers controlling them, and ideal continuous-to-discrete and
discrete-to-continuous transformers.
As a prerequisite, the ideal reader would know multivariable analog control
design, especially H2 and H-infinity theory---a user's guide to H2 and
H-infinity theory is presented in Chapter 2.

CALL FOR PAPERS
Neural Networks and Fuzzy Systems
for
Closed-Loop Control Applications
A Special Issue of:
"Journal of Intelligent Control and Systems"
Special Issue Editors:
F.L. Lewis and K. Liu
Automation and Robotics Research Institute
The University of Texas at Arlington
7300 Jack Newell Blvd. S
Ft. Worth, Texas 76118-7115
Papers are solicited for a special issue on Neural Networks and Fuzzy
Systems for Closed-Loop Control Applications of the "Journal of Intelligent
Control and Systems". Both short papers and regular papers are desired. The
format of JICS is identical to that of IEEE Transactions.
Intelligent controllers have the potential to significantly improve the
performance of complex nonlinear processes. Neural networks and fuzzy
systems have been applied with considerable success in digital signal
processing, decision-making, classification, and other open-loop
applications. However, closed-loop control applications of neural networks
and fuzzy systems have generally been ad hoc, with no repeatable design
algorithms or proofs of guaranteed stability. In spite of the lack of
rigorous techniques for intelligent control system design, neural network
and fuzzy system controllers have enjoyed remarkable success in complex
control applications. This motivates one to use mathematical approaches to
provide understanding and to shed light on further possibilities. It is the
proofs that yield valuable information concerning: (1) the structure of the
neural or fuzzy control system, (2) modified learning rules that keep
tracking errors small and adaptive parameters bounded, and (3) additional
control input terms that ensure robustness against unforseen disturbances.
Without guaranteed performance, acceptance of intelligent controllers by the
control systems community and US industry will not be forthcoming.
Therefore, this special issue will focus on closed-loop control applications
of neural networks and fuzzy systems that offer repeatable design algorithms
and mathematical proofs of stability and performance. Papers that present
simulations following nonrigorous discussions cannot be included. The
objective of this special issue is to provide a forum for developing
paradigms for intelligent control systems in the sense of T.S. Kuhn's
"Structure of Scientific Revolutions".
The Special Issue will appear in early 1996. Four copies of manuscripts
should be submitted for review by 15 July 1995:
Neural net papers should be addressed to F.L. Lewis
817-794-5972, fax 817-794-5952, flewis@controls.uta.edu
Fuzzy systems papers should be addressed to K. Liu

International Journal of Robust and Nonlinear Control
Announcement
Call for papers for a Special Issue on
TWENTY YEARS OF FEEDBACK LINEARIZATION OF NONLINEAR SYSTEMS
The study of the transformation of a nonlinear system \dot{x} = f(x,u) under
a static state feedback u = \alpha(x,v) and a coordinate change z = Z(x)
into a controllable linear system \dot{z} = Az + Bv has been initiated by
V.I. Korobov (1975) and R.W. Brockett (1978). Afterwards many papers have
been published in relation to this question, first dealing with the above
static state feedback linearization and, very recently, on the linearization
problem under dynamic state feedback. The International Journal of Robust

The Image and Multidimensional Signal Processing Technical
Committee of the IEEE Signal Processing Society has established a
tradition of biennial workshops that have been intellectually
stimulating and held in interesting places. The Ninth Workshop,
to be held in cooperation with the Society for Imaging Science
and Technology continues this tradition. It will be held in
Belize which is located on the Caribbean Sea directly south of
the Yucatan Peninsula and east of Guatemala, just two hours by
plane from Miami. Belize has a subtropical climate. The workshop
will take place in the dry season when temperatures will average
22C. There are beautiful Mayan ruins in Belize and the longest
barrier reef in the Western Hemisphere. The workshop will be held
in Belize City at the Radisson Hotel.
The theme of the workshop is ``Model-Based Methods in Imaging:
This was partly motivated by the NSF-sponsored workshop on Future
Directions in Signal Processing that was held in Keystone, Colorado
in November 1991. At this workshop,the task group in the IMDSP
area identified a need for more emphasis on model-based methods,
including models for signal content and models for the human
viewer. In addition, it was felt that there was a need for more
work on image quality metrics. It is the intention of this workshop
to address these topics:
Physics-based models
Multiresolution models
Models for the human visual system
Color models
Image and video quality metrics
Image and video compression
Image and video analysis
Image rendering for printing and display Color imaging
Radar imaging
Medical imaging

CONFERENCE
CONTROL OF INDUSTRIAL PROCESSES:
SYNTHESISING THE STATISTICAL AND ENGINEERING APPROACHES
19 - 20 SEPTEMBER 1995
UNIVERSITY OF HERTFORDSHIRE
CALL FOR PAPERS
Historically there have been two distinct approaches to the control of
industrial processes: that of the statistician and that of the engineer.
Statistical Process Control techniques were developed by statisticians for
use in the parts industry while Automatic Process Control techniques were
developed by engineers for use in process industries. The sharp lines
dividing these industries have recently begun to dissolve bringing control
engineers and statisticians into closer contact with each other. This
conference aims to provide control engineers and statisticians with an
opportunity to exchange ideas about integrating the two approaches to
Process Control.
The conference ( originally suggested by the Quality Improvement
committee of the Business and Industry section of the Royal Statistical
Society ) is being organised jointly by the University of Hertfordshire
Business School, the City University School of Mathematics, Actuarial
Science and Statistics, and the University of Newcastle Department of
Engineering Mathematics.
There will be four half day sessions entitled: Overview; Process modelling;
Process control; Forward with new thinking. Each session will be introduced
with a keynote talk and will be followed by a number of shorter invited and
contributed case studies. Peter Caines (McGill University) and Julian Morris
(Newcastle University) have agreed to introduce the Overview and Forward
with new thinking sessions. The title of Professor Morris' talk is
"Modelling human intelligence to solve engineering problems". Invited
speakers include: Tom Fearn (University College London) on "A case study on
experimentation in the food industry", Luc Pronzato (University of Nice),
Ron Leigh (University of Westminster) on "Adaptive control of multivariate
batch processes using digital models" , Ming Tham (Newcastle University) on
"A practical application of adaptive control", and Mike Grimble (University
of Strathclyde) "Advanced control and simulation techniques for the
manufacturing and process industries"
Titles and abstracts for contributed papers should be sent, as soon as
possible, to:

Glasgow, Glasgow, Scotland.
The project is a study of the fundamental properties of neural
network based adaptive control systems. Where possible, links
with traditional adaptive control systems will be exploited. A
major aim is to develop a systematic engineering procedure for
designing neural controllers for non-linear dynamic systems. The
techniques developed will be evaluated on concrete industrial
problems from within the Daimler-Benz group of companies:
Mercedes-Benz AG, Deutsche Aerospace (DASA), AEG and DEBIS. The
project leader is Dr.~Ken Hunt (Daimler-Benz) and the other
principal investigator is Professor Peter Gawthrop (University of
Glasgow).
