Dear Colleagues,

We have recently published the book

QUALITATIVE THEORY OF DYNAMICAL SYSTEMS - The Role of Stability Preserving
Mappings, by Anthony N. Michel and Kaining Wang, Marcel Dekker, New York,
1995 (x + 450 pp).  (Pure and Applied Mathematics Series)

The book is primarily concerned with the Lyapunov stability of general
dynamical systems.  The treatment is applicable to finite and infinite
dimensional systems, including systems that cannot be characterized by
equations, inequalities and inclusions.

The usual approach of developing the Lyapunov theory for dynamical systems
relies on generalized energy (or generalized distance) arguments.  In
contrast to this, the approach advocated in the present book makes use of
STABILITY PRESERVING MAPPINGS (which establish qualitative equivalences
between dynamical systems) to develop the subject on hand.

BALANCED CONTROL OF FLEXIBLE STRUCTURES
by Wodek Gawronski

Published by Springer Verlag, London
(Lecture Notes in Control and Information Sciences, vol.211)


This book provides analysis and design tools for the control of 
flexible structures. It explains the balanced techniques, derives the 
properties of flexible structures in the open- and closed-loop 
configuration, and presents a uniform approach to open- and closed-loop 
analysis and design.

                        Nonlinear Systems
                         Second Edition
                        Hassan K. Khalil
                         Prentice Hall

This is the second edition of the textbook Nonlinear Systems which was
published in 1992 by Macmillan. The book is available for the term
starting in January, 1996. The order should specify the second edition.

The second edition is different from the first one in three aspects:

1. The material of the book has been reorganized into analysis vs
design chapters. The first nine chapters deal with nonlinear analysis
tools that apply to general nonlinear systems.  Chapter 10 presents
analysis tools for feedback systems. The last three chapters deal with
control design for nonlinear systems.

2. There is an expanded coverage of some material as well as coverage of 
new topics not included in the first edition. The new topics include:
        Passivity approach to analysis of feedback systems.
        Gain scheduling
        Backstepping
        Sliding mode control

The expanded coverage includes:

        Input-output stability (including L2 gain)
        Design via linearization (including output feedback and 
                integral control)
        Feedback linearization (including input-output linearization
                and differential geometric approach)

3. New exercises have been added, bringing the total number of exercises 
to over 400, many of which are multiple-part exercises. A solution manual 
is available from the publisher for instructors. 

The complete table of contents is given below.

This special issue is devoted to recent developments in hybrid control
system modeling, analysis and synthesis.  

Hybrid systems contain two distinct types of components, subsystems with
continuous dynamics and subsystems with discrete event dynamics, that
interact with each other.  Hybrid systems are models for networks of
digital and continuous devices, in which digital control programs sense and
supervise continuous and discrete plants governed by differential or
difference equations.  

Hybrid control systems are typically found when continuous processes
interact with, or are supervised by, sequential machines.  Such systems
frequently arise from computer aided control of continuous processes and
such hybrid systems arise in varied contexts such as manufacturing,
communication networks, autopilot design, computer synchronization, traffic
control, and industrial process control, for example.  Another important
way in which hybrid systems arise is from the hierarchical organization of
complex control systems.  In these systems, a hierarchical organization
helps manage complexity and  higher levels in the hierarchy require less
detailed models (discrete abstractions) of the functioning of the lower
levels, necessitating the interaction of discrete and continuous
components.  Examples of such systems include flexible manufacturing and
chemical process control systems, interconnected power systems, intelligent
vehicle highway systems, air traffic management systems, computer
communication networks.  More generally, hybrid systems arise from the
interaction of discrete planning algorithms and continuous control
algorithms.  As such, hybrid systems provide the basic framework and
methodology for the synthesis and analysis of autonomous and intelligent
systems.  Examples of this type not already mentioned above include
biological motor control models, robotic systems, data base retrieval
systems, medical informatics systems.  


Since the continuous and discrete dynamics coexist and interact with each
other it is important to develop models that accurately describe the
dynamic behavior of such hybrid systems.  In this way it is possible to
develop control strategies that fully take into consideration the relation
and interaction of the continuous and discrete parts of the system.  In the
past, models for the continuous and discrete event subsystems were
developed separately; the control law was then derived in a rather
empirical fashion, except in special cases such as the case of digital
controllers for linear time-invariant systems.  The study of hybrid control
systems is essential in designing sequential supervisory controllers for
continuous systems, and it is central in designing intelligent control
systems with a high degree of autonomy.  It also provides the backbone for
the formulation and implementation of learning control policies.  In such
policies, the control acquires knowledge (discrete data) to improve the
behavior of the system as it evolves in time.  

Hybrid systems has become a distinctive area of study due to opportunities
to improve on traditional control and estimation technologies by providing
computationally effective methodologies for the implementation of digital
programs that design or modify the control law in response to  sensor
detected events, or as a result of adaptation and learning.  


The main emphasis in this special issue is on fundamental results in
modeling and analysis, and on synthesis methodologies for hybrid control
systems.  Application of results to real life examples is encouraged. 
Before submitting, prospective authors should consult past issues of the
Transactions on Automatic Control to identify the type of results and the
level of mathematical rigor that are the norm in this journal.  


The papers are due by July 1, 1996 and should be sent to Panos Antsaklis. 
Notification of acceptance will be sent by December 31, 1996.  The special
issue is targeted for 1997 or early 1998.  All papers will be refereed as
per IEEE Guidelines.  

Please consult the inside back cover of any recent issue of the
Transactions on Automatic Control for style and length of the manuscript
and number of required copies (seven copies with cover letter) to be sent

--------------------------------------------------

Scope of the Symposium:

ISMCR'96 is the 6th edition in a series of international conferences on
Measurement and Control in Robotics; this event which will be held in
Brussels succeeds ISMCR'95 held in Slovakia on 12-16 June 1995.

The objective of this symposium is to bring high quality papers on relevant
topics for reporting new research results, together with
cross-fertilization among experts in each speciality.

Today's robots can be considered as advanced mechatronic motion systems
that combine mechanics, actuation and control, to achieve complex tasks
with computer interaction. These mechatronic devices are often combined
with sensory systems and sequential control to obtain complex production
systems. Different sensors such as ultrasonic, vision camera, laserbeam
equipment atso are combined to obtain better and more reliable information.
The fact that problems are encountered during the extraction of the
required information from the multiple sensors, is described as sensor
fusion requirements.

The complexity of all these applications put new demands to the performance
of the interface systems to the programmers or operators of such systems.
The need for improvement can also be observed at the equipment level. The
increased demand for accuracy for surgery or for dynamic applications where
the robot is not static for example, has revealed the limitations of actual
robots. More accurate motion control is still required. The robots must be
calibrated or recalibrated using state-of-the-art calibration systems if
high accuracy is required. The application of robots for special
technologies is limited by the availability or the performances of sensors.
The new sensors have to fulfil requirements of size (miniaturisation),
strength, robustness (hazardous environments). These different aspects and
some more special applications of robots such as in space or in home can be
found in the list of the main topics below.

1. AIMS OF THE SCHOOL
A summer school on the modelling and control of mechanisms and robots is
organized in the period July 22-26, 1996, at the residential centre of
Universita` di Bologna, in Bertinoro, (Forli`), Italy. Aims of the school
are:

- to provide doctorate students and professionals with basic and advanced
  material on modelling and control of complex mechanical systems, with
  particular emphasis on robotic manipulators, so to discuss and identify
  open problems and future research directions;

- to bring together young persons active in robot control and related
  fields and give them the opportunity of knowing each other.

Besides the activity during the teaching hours, in a consistent part of
the school software tools will be used for demonstrative and (simulative)
experimentation of the illustrated concepts. Moreover, the participants
will be asked to solve a collection of problems and, at the end of the
programme, to present a little report on a given topic on a selected
argument of the School. 

The notes of the school will be published in the book "Modelling and
Control of Mechanisms and Robots", C. Melchiorri, A.  Tornambe` Eds., to
be published by World Scientific Publishing, Ltd..

During the school, a technical workshop will be held on July 26, 1996,
presenting ongoing research results achieved in the framework of the ERNET
initiative. Moreover, a poster session will be organized for the
participating students, who will have the possibility of presenting their
research activity.

The number of students is limited to 50, and a pre-registration before May
1, 1996, is mandatory. The participants will be accepted in the order
received.  The school will be held in the residential centre of
Universita` di Bologna, located in three large historical buildings placed
on the top of the built up area of the ancient town of Bertinoro.  The
centre consists of: living quarters (60 beds in single and double rooms),
a teaching center, computer centre (20 work stations), lecture hall and
self service canteen.  All the activities (i.e., lessons, lunches and
livings) will take place in the center. 

In order to cover the expenses, a registration fee is asked. The fee is
comprensive of half-board accomodation (breakfast, lunch, bed) for 6 days,
the lecture notes and the book, the social dinner on Thursday, July 25,
and the participation to the technical meetings on Friday 26. The fee is
650.000 Italian Liras for academies and 1.000.000 Italian Liras for
industries. For a limited number of students from the East Countries of
Europe the fee is 100.000 Italian Liras (in this case, send a brief CV).

2. SCHOOL TOPICS
Modelling of Mechanical Systems; Kinematics of Robots; Control of
Hamiltonian Systems; Elastic and Flexible Robots; Telemanipulation; The
Contact Problem in Classical Mechanics; Force Control; Technologies and
Methodologies for Motion Control. Each topic will be presented and
discussed also with the use of CACSD tools.

3. WHO SHOULD ATTEND
The school is mainly intended for doctorate students and young
professionals engaged in the design and use of complex mechanical systems
(such as robots), with a particular emphasis on the modelling and control
aspects of these devices.

4.  PREREQUISITE 
Undergraduate level courses on feedback control and robotics are suggested
as adequate preparation for this school. 

5. AWARD
At the end of the school, a presentation of one of the topics of the
school will be given by the participating students. The best presentation
will be awarded with a special prize. It is planned to include a selection
of the presentations in a volume, along with the ERNET technical papers.

        11th IEEE International Symposium on Intelligent Control (ISIC-96)

                         FINAL CALL FOR PAPERS

                        September 15-18, 1996
            The Ritz-Carlton Hotel, Dearborn, Michigan, USA

        
Sponsored by the IEEE Control Systems Society and held in conjunction with:

The 1996 IEEE International Conference on Control Applications (CCA)
and
The IEEE Symposium on Computer-Aided Control System Design (CACSD)



ISIC General Chair:     Kevin M. Passino, The Ohio State University
ISIC Program Chair:     Jay A. Farrell, University of California, Riverside
ISIC Publicity Chair:   Marios Polycarpou, University of Cincinnati


        Intelligent control, the discipline where control algorithms are
developed by emulating certain characteristics of intelligent biological
systems, is being fueled by recent advancements in computing technology and
is emerging as a technology that may open avenues for significant
technological advances.  For instance, fuzzy controllers which provide for
a simplistic emulation of human deduction have been heuristically
constructed to perform difficult nonlinear control tasks.  Knowledge-based
controllers developed using expert systems or planning systems have been
used for hierarchical and supervisory control.  Learning controllers, which
provide for a simplistic emulation of human induction, have been used for
the adaptive control of uncertain nonlinear systems.  Neural networks have
been used to emulate human memorization and learning characteristics to
achieve high performance adaptive control for nonlinear systems.  Genetic
algorithms that use the principles of biological evolution and "survival of
the fittest" have been used for computer-aided-design of control systems
and to automate the tuning of controllers by evolving in real-time
populations of highly fit controllers.

        Topics in the field of intelligent control are gradually evolving,
and expanding on and merging with those of conventional control.  For
instance, recent work has focused on comparative cost-benefit analyses of
conventional and intelligent control techniques using simulation and
implementations.  In addition, there has been recent activity focused on
modeling and nonlinear analysis of intelligent control systems,
particularly work focusing on stability analysis.  Moreover, there has been
a recent focus on the development of intelligent and conventional control
systems that can achieve enhanced autonomous operation.  Such intelligent
autonomous controllers try to integrate conventional and intelligent
control approaches to achieve levels of performance, reliability, and
autonomous operation previously only seen in systems operated by humans.

        This year the ISIC is being held in conjunction with the 1996 IEEE
International Conference on Control Applications and the IEEE Symposium on
Computer-Aided Control System Design.  Effectively this is one large
conference at the beautiful Ritz-Carlton hotel.  The programs will be held
in parallel so that sessions from each conference can be attended by all.
There will be one registration fee and each registrant will receive a
complete set of proceedings.  For more information, and information on how
to submit a paper to the conference see the back of this sheet.

OBJECTIVES

The planned NATO Advanced Study Institute aims at creating an opportunity
for the engineers and the scientists working in the area of Soft Computing
to come together in an informal atmosphere and to discuss and disseminate
knowledge on the application asp ects of soft computing techniques,
especially in intelligent control systems and mechatronics. Two particular
areas that the institute will put a special emphasis on are (1) how to
achieve a synergetic combination of the three constituents of soft
computing (2) how can such a combination be applied to achieve a high
Machine Intelligence Quotient. The latter will include a critical
investigation of existing applications. Hardware realization possibilities
in the form VLSI chips will also be addressed. 

WHAT IS AN ASI?

The objectives of ASIs is to disseminate advanced knowledge not yet in
university curricula and foster scientific contacts through high level
