Lectures on Nonlinear Control Systems
Dr. S. Nikitin
This course of lectures will be offered in a regular class room (TTh.
4:40-5:55pm) and on the Internet at
http://lagrange.la.asu.edu
http://www.m-and-s.com
The lectures will be based on the book of Dr. S. Nikitin. The course starts
in August, 25th and goes till December. You can register for the course by
sending el-mail at
"nikitin@asu.edu"
or
"mandsgroup@m-and-s.com"
with the message
"register for MAT 598".
If you are a student at Arizona State University then you can register by
phone
(602)350-1500
You need to register for the course with the line number 46631.
This course of lectures on nonlinear systems was given by Dr. S. Nikitin at
the Moscow State University (1989 - 1990), at the Moscow Institute of Steel
and Alloy (1990 - 1991), at the Kaiserslautern University (summer 1990, 1991
- 1992), and at the Arizona State University (fall 1996). The main purpose of
this course is to provide a self-contained, complete and geometrically clear
presentation of recent results on global controllability and stabilization.
A good deal of effort was put into the development of geometrical control
intuition and inspiring the reader to think independently. That is why, the
course contains many geometrical illustrations and exercises.
The material presented will be organized in such a way that it is only
assumed that the reader has mastered the very basic notions of ordinary
differential equations theory, general topology and analytic geometry.
The main topics covered in the course are
* Controllability analysis under phase and control constraints
* Control Synthesis
* Feedback Stabilizer Design
* Nonlinear Observer Design

RESEARCH ASSOCIATESHIP
Applications are invited for a Research Associateship to work on an EU
funded (ESPRIT) Long Term Research project involving the application of
co-operating agents within the domain of manufacturing control systems. The
project, which began on 1 February 1997, is a three year project involving
five European industrial and academic partners. The focus of the project is
specifically on manufacturing control systems that are capable of handling
the increasingly frequent disturbances and changes that production must cope
with to be effective.
The appointment will be for 30 months starting 1 August 1997 and the
candidate will be expected to be able to work independently and
collaboratively to develop appropriate control tools, integrate these into
distributed test bed simulations, and develop system features which would
enable effective implementation of the results. It is hoped that the
successful candidate will have previous experience in the manufacturing area
or in sectors where distributed systems management is equally important.
Candidates should have a good honours degree and preference will be given to
candidates with a degree in a relevant subject. Knowledge of modelling,
scheduling and control techniques for discrete manufacturing systems would
be a significant advantage. It is important that the candidate is well
versed in computer programming and networking in a Windows environment.
Experience with some or all of C++, Matlab, factory simulation and languages
suitable to agent-based programming would also be an advantage.
Further particulars and an application form can be obtained from Dr Duncan
McFarlane, Manufacturing Engineering Group, Department of Engineering,
University of Cambridge, Mill Lane, Cambridge, UK, CB2 1RX or by email at
dcm@eng.cam.ac.uk. Closing date for applications is 2 May 1997.
The University follows an equal opportunity policy.

DESCRIPTION
Designed for a challenging, one-semester systems course, this book is an
introduction to systems theory, with an emphasis on control theory. It
examines the fundamental properties that govern the behavior of systems by
developing mathematical descriptions of systems. The depth and breadth of
coverage enables the reader to easily progress to more advanced topics in
the systems area. This textbook presents a broad view of linear systems,
their advantages and limitations and covers linear time-invariant,
time-varying, continuous-time, and discrete-time systems. It also contains
extensive coverage of stability and polynomial matrix/fractional
representation, topics that prepare students for further study in linear
and nonlinear feedback control. Flexible coverage allows the independent
study of time-invariant and time-varying systems as well as continuous-time
and discrete-time systems. The book contains extensive mathematical
background material, it is self-contained and it can be used for self-study
or as a reference.

This is a republication of a book first published by Prentice Hall in
1989 that is now out-of-print. It is a comprehensive and theoretically
sound treatment of parallel and distributed numerical methods. It
focuses on algorithms that are naturally suited for massive
parallelization, and it explores the fundamental convergence, rate of
convergence, communication, and synchronization issues associated with
such algorithms.
Among its special features, the book:
-----------------------------------------------------------------------
** Quantifies the performance of parallel algorithms, including the
limitations imposed by the communication and synchronization penalties.
** Describes communication algorithms for a variety of system
architectures including tree, mesh, and hypercube.
** Provides a comprehensive convergence analysis of asynchronous methods
and a comparison with their asynchronous counterparts.
** Covers direct and iterative algorithms for linear and nonlinear
systems
of equations and variational inequalities.
** Describes optimization methods for nonlinear programming, shortest
paths, dynamic programming, network flows, and large-scale
decomposition.
** Includes recent research material on optimization methods,
asynchronous algorithm convergence, rollback synchronization,
asynchronous communication network protocols, and others.
** Supplements the text material with many exercises (solutions manual
publicly available).

Universite de Reims Champagne-Ardenne
CO-SPONSORED BY : BIRA, INRIA, CNRS, EUREL, Club EEA, EAEEIE
SCOPE
Automation can nowadays no longer be either continuous or discrete. Coping
with: various operating modes, increased flexibility and dependability
constraints, batch processes, and controlling production flow, demand a
broad approach combining the concepts, models, theories, and know-how both
from continuous control systems, and from discrete-event systems.
The expressions Mixed processes or Dynamic Hybrid Systems designate the
class of systems that explicitly and simultaneously include continuous and
event based phenomena or models.
Following the success of the two previous conferences ADPM'92 (held in
Paris) and ADPM'94 (held in Brussels), the Dynamic Hybrid Systems working
group of the AFCET/SEE has taken the initiative of organising the 3rd
international Conference ADPM'98 in Reims, on March 19th and 20th 1998. This
conference has the twofold objective of providing a survey of the advances
in this field and of setting up contacts between researchers and
industrials, whether they have control, electronics or informatics
background. The material submitted must be original and related to one of
the theoretical or practical aspects of modelling, analysis or synthesis of
hybrid systems.
TOPICS
Modelling:
- Event based models: automata (timed, hybrid, ...), Petri nets (continuous,
batch, hybrid, high-level, ...), Statecharts, Grafcet, transition systems.
- Continuous based model: linear or non-linear processes, discontinuous
state or transfer function models, algebraic models, bond-graphs.
- Logic, temporal, stochastic, chaotic models.
- Methodological issues for hybrid systems: multi-modelling approaches,
hierarchical organisation, distribution of intelligence.
Simulation, Analysis and Synthesis:
- Simulation and proof of specifications and implementations.
- Properties of hybrid systems: Controllability, Observability, Stability,
Robustness, Reliability, Safety.
- Synthesis, identification and supervision of hybrid systems: intelligent
control, adaptive control, optimal control.
Applications:
- Examples of specially adapted automation components: batch programmable
controllers, field buses, communication networks, software systems.
- Industrial processes: electronic systems, batch processes, manufacturing
systems, complex systems, ...
- Hybrid systems in education and training.
Please include the names, complete mailing addresses, phone number of the
authors, eventually e-mail number. Underline the name of the corresponding
author. Abstracts and final papers may be submitted in French or English.
All the accepted papers will be included in the conference proceedings. A
further selection will be made to include:
- 10 papers in a special issue of the European J. of Automation.
- 6 papers in the journal Revue de l'Electricite et de l'Electronique.
TRAVEL
Reims is situated 150 Km to the east of Paris. It has a direct connection by
shuttle car with both Paris airports: Roissy and Orly. The railway station
and the A4 and A26 motorways are situated at about 200 meters of the
Congress Centre.
During the conference an exhibition of relevant hardware tools, software
tools, and batch processes will take place.
The first national forum for students of Electronics, Power, and Control
Engineering will also be held in conjunction with the conference.

LAST Call for Papers:
SPECIAL SESSION ON LEARNING CONTROL
-----------------------------------
at the
WORLD MULTICONFERENCE ON
SYSTEMICS, CYBERNETICS AND INFORMATICS (SCI'97)
Caracas, Venezuela
July 7-11, 1997
(Extended Deadline for Abstracts: March 31, 1997)
LEARNING CONTROL
----------------
"Learning Control" is a term attributed to a broad class of self-tuning
processes, where the performance of the controlled system with respect
to a particular task is self-improved based on the performance for
previous identical tasks. The idea of self-learning control systems is
aesthetically appealing and represents a fundamental step towards fully
autonomous systems. This is of advantage when dealing with uncertain or
changing systems.
The major difference between adaptive and learning control is sometimes
characterized in terms of 'local' and 'global' learning. An adaptive
systems continuously adapts to changes in environment and system para-
meters (local), whereas a learning systems memorizes and recognizes
previously experienced situations (global). The classification of
learning control will be one of many topics at this SCI'97 session. We
invite you to present your recent research results, learn about current
avenues in the field, and to meet interesting people.
We look for quality papers which cover the topics outlined below.
Similar work is also welcome.
OVERVIEW OF SCI'97
------------------
SCI'97 is a truly multi-disciplinary conference, covering intelligent
computing, information theory, cybernetics, social and biological
systems, psychology, and applications. General information about the
conference is listed below or can be found at the website
http://www.iiis.org/
SCI'97 is an ideal platform for a special session on "Learning Control",
an emerging discipline which is receiving more and more attention from
both the academic and industrial controls community, due to the increasing
complexity of (technical) systems.
TOPICS
------
The Learning Control Session will include, but is not limited, to the
following topics (further suggestions are encouraged):
* Classification of learning control systems.
* Mathematical learning theory in a controls context.
* Biological or social self-learning control mechanisms and
their extension to technical systems.
* Human operator modeling.
Human operators are (currently) the ultimate learning controller
for complex systems.
* Neurocontrol, using biological or artificial neural networks.
* Fuzzy logic and learning.
* Optimal Control type learning algorithms (adaptive critics,
Q-learning, etc.).
* Variable structure learning of controllers and its
variants, e.g. reconfigurable and reparameterizable controllers.
* Stability of learning control systems (important!).
* Hardware implementations.
* Applications and case studies which exceed the usual benchmark
problems towards real-world complex systems.
Questions about, or contributions to this special session can be
e-mailed to Karl Mathia at

6th IFAC Symposium on Automated Systems Based on Human
Skill - Joint Design of Technology and Organisation
Sept 17-19, 1997, Kranjska gora, Slovenia
Scope of the Symposium:
As the previous five Symposia of the same name, this
Symposium will bring together researchers, developers and users
of automated systems. The areas of discussion are:
- the role of the individual human operator at the work place
(human-machine interaction, skills, motivation, health,
creativity, quality of working life, ...)
- work-groups supported by technology (human
communication, cooperation, participation in decision
processes, decision-support systems, ...)
- networks of groups and enterprises, together with the
supporting networks of information, control and
transportation systems (computer - supported cooperative
work, virtual enterprises, issues of reengineering of complex
hardware and software, technology and quality management,
...)
- the impact of control and information technology on society at
large (issues of national strategies, employment and
qualification, education and training, the roles of trade unions,
gender issues, ...)
- the impact of technology on the natural environment.
The Symposium will discuss these aspects in the following
areas of using control technology:
1) Manufacturing and Processing
2) Energy systems
3) Transportation
4) Business processes
The Symposium takes place in Slovenia specifically in order
to encourage participants from the newly independent states of
Europe to join the IFAC activities. Slovenia is easily reached
from any part of the world.
Preliminary Programme Outline:
The members of the IPC and NOC thank cordially the authors of the
papers submitted to date. Preliminary scanning revealed that there
will be an interesting event comparable in quality to the previous
symposia in this series. Please, find some details from Programme
planning below.
Plenary papers foreseen, given by reputable speakers:
