Impact of Artificial Intelligence Methods and Models on Engineering Practice
The workshop on Artificial Intelligence Methods and Models
took place in Warsaw during two December days, just at the
beginning of the second decade of that winter month. Apart
from all the administrative matters, the necessity to organize
sessions, where papers were presented, our main and initial
idea was to find out new paths and traps or, if necessary, to
attempt to built certain small bridges between theory and
practice, methodology and experiments, new concepts and
past experience. But a smaller scale the target was to develop
opportunities for new links between those who are a long way
apart, those working upstairs and those staying downstairs
who rarely talk between themselves. We liked to bring
together our colleagues from Warsaw and other Polish cities
and get some stimulation from our European friends.
There is a common feeling that artificial intelligence methods
and models have been successfully present in our scientific
and engineering life for some time now. But fundamental
questions are still being stated and discussed. In our
presentation at least two speakers addressed that type of
questions to the audience.
We are discussing with Prof. Teresa Orłowska-Kowalska the day of birth of multivalued logic
Prof. Teresa Orłowska-Kowalska from Wrocław University
of Technology was talking about artificial intelligence methods
in identification and control of electrical drives. She herself is
a good example of a scientist who is involved in both
theoretical research and practical applications. She attracted
attention of a large number of our Ph.D. students. Her very
engineering-oriented tutorial sparkled a closed-circle
discussion about fundamentals. Coffee break was fulled with
various problems of multivalued logic and its origin. The
comments on historical facts were going back to 1931.
Prof. Bernardete Ribeiro came from the oldest, beautiful and
for long time the only Portuguese University Coimbra. The
University is 100 years older than Polish Jagiellonian
University. Prof. Ribeiro presented an invited paper about
computational intelligence and its applications. The scope of
the term “computational intelligence” used in the paper could
be treated as quite similar to other terms including artificial
intelligence. Let us look at the formulations. “The field of
Computational Intelligence (CI) comprises well established
technologies of neural networks, fuzzy systems, evolutionary
computation and other adaptive and biologically motivated
computational paradigms. The importance of these methods
and the reason for their considerable potential in solving real
world problems lies in their ability to enable or facilitate
intelligent behavior in complex and changing environments.
As such they succeed in problems that have been difficult to
solve by classical mathematics”. Bernardete Ribeiro has an
extended educational interdisciplinary background and
experience from various fields: chemical engineering,
electrical engineering, informatics and bioengineering.
The audience attending the tutorial of Prof. Carlo Cerati
Prof. Carlo Cecati came to join us from L’Aquila University
located in the centre of Italy, just next to Grand Saso. L’Aquila
is a charming, medieval town inhabited by nice people. He
was talking for two hours about passivity based control of
induction motor. The majority of our Ph.D. students attended
this tutorial.
Prof. Tadeusz Kaczorek has presented an invited paper about
relationship between something which can be treated
as electrical engineering fundamentals i.e. the circuits and
believed complicated contemporary theoretical achievement –
the singular compartmental systems. The paper was
presented with passion and accuracy. He finished exactly
on time without looking at the watch.
Our Ukrainian friend Ihor Isayev came to us from Lvov. He
attracted our attention talking about probabilistic analysis of

stochastic systems. Our Workshop was opened to everybody
and was attended every day by more than 30 people. We had
15 minutes long regular papers, 1 hour long invited papers,
and tutorials - 2 and 2.5 hours long, in total - 20 papers within
two days. Many our colleagues came from Gdynia, Łódź,
Wrocław, and Zielona Góra. The sessions were devoted to
image processing, approximation and control, robotics and
artificial intelligence applications. Many papers were
interesting and inspiring. I would like to mention the one of
Dominik Sierociuk who constructed home made robot (no
name was given to it so far) with infra-red sensors and
navigation algorithm employing Kalman filter (extended!)
navigating around his flat. The computational task was easy
for this little creature just to invert 23x23 matrix occasionally!

You will be able to read most of the presented papers in our
post Workshop publication in Polish Journal “Przegląd
Elektrotechniczny” (Electrotechnical Review) in this year April
issue.
Workshop dinner
Our Workshop Dinner took place in friendly atmosphere in an
old Polish Manor House which is surrounded by 20-hectare
English style park with a vast pond and situated 12 km from
the centre of Warsaw.

Chair of PELINCEC Working Group 3
PELINCEC Seminar on Harmonic Distortion in Power Systems
First seminar organized by Working Group 1 - Power Quality -
was devoted to one of the most actual problems occurred
in electrical power systems supplying more and more
converters which draw from line distorted currents. Opening
the session PELINCEC Director Prof. M. P. Kazmierkowski,
after short introduction gave floor to Prof. Roman Barlik –
head of Working Group 1. The first speaker, which had a
significant contribution to arrange the meeting and preparing
the program, was Professor Zbigniew Hanzelka from
University of Science and Technology – AGH – Krakow. In his
lecture Prof. Hanzelka pointed out the most important
problems of harmonic measurement, phenomenon of inter-
harmonics and some methods of their mitigation. The last
conclusion of Prof. Hanzelka lecture was a message that in
the computer and multimedia era broad development of line
friendly single-phase low power supplies seemed to be one of
the most important goals.

M. P. Kazmierkowski
Next presentation provided by team Andrzej Bień and
Krzysztof Duda from Measurement Department AGH –
Krakow showed some sophisticated methods of spectral
analysis used for line current and voltage harmonic distortions
measurement. A very interesting lecture was delivered by
Prof. Jan Desmet from Department P.I.H of Hogeschool West-
Vlaandern, Belgium, showing some important facilities
of distorted voltages with regard to neutral conductor
problems. Also a huge power loses caused by voltage
harmonics in cable of supply line were explained and
underlined. Other practical example of power supply
compensation in case of varying load was presented and
discussed by Prof. Yuri Varetski from Lviv Polytechnic State
University. Finally, another team of Henryk Koseda and Marek
Okasiński from Electrical Power Institute in Gdansk showed
a rich package of harmonic measurements done in high
voltage Polish grid. The seminar was attended by over
60 participants.

Project Oriented Teaching in Power Electronics and Drives
PELINCEC seminar by Professor Frede Blaabjerg
The Aalborg University in Denmark is known from the experimental teaching
methodologies. From the very beginning (since 1974) Aalborg University has been
carrying out teaching based on problem-oriented and project-based learning. From
the moment the students start studying till they finalize their final project, they work in
teams all the time. In his lecture on December 18, 2003 Professor Blaabjerg at first
presented Aalborg University, Institute of Energy Technology. Next, the general
teaching approach at Aalborg University with special emphasis on the Master
Program taught in English in Power Electronics and Drives was discussed. Of
course, implementation of the project-based learning requires spaces and equipment
for every student. However, it was proved by external evaluators that - in comparison
to conventional universities - graduate of the Aalborg University is better prepared for
team work, solution of new problems as well as for interdisciplinary approach.
Photovoltaic and Wind Energy in Distributed Power
Systems PELINCEC seminar by Professor Frede Blaabjerg
Prof. Frede Blaabjerg presenting his Short Course
In the second part of his activities in Warsaw Professor Blaabjerg presented 4-hours
seminar devoted to “very hot” topic Power Electronics in photovoltaic and wind
energy generation. As we know, the electrical power generation is undergoing a
major restructuring; one aspect being the transition from large power generating
plants to smaller distributed power plants, often based on alternative energy sources.
Distributed Power Generation Units (DPGU) today are mostly based on wind turbine
systems, photovoltaic systems, micro turbines and fuel cells. The power range
of individual units varies from 100 W to 4 MW or more. Common to all installations is
the fact that the DPGUs operate autonomously. However, with a high penetration of
DPGUs into the electric grid, power system stability problems may appear. Power
Electronics is the enabling technology which allows flexible interconnection of
DPGUs to the electric grid. Primary focus in the presentation was on wind turbines
and photovoltaic, including technical development, the use of power electronics and
some industrial examples. Over 40 participants, mainly PhD and MSc students,
attended this Short Course.

Control of Variable Speed Electric Generators: Present Status and
Perspective PELINCEC seminar by Professor Ion Boldea
The Seminar, presented by an excellent speaker Professor Ion Boldea, took place in the seminar Room of the Old Boiler House, Warsaw University of Technology on December 15, 2003. It explored the present status of topologies,
performance, modeling, control and design of variable speed generators including induction, IPM, switched-reluctance, high speed PM, and double-fed induction generators. This extensive presentation showed theoretical and experimental results from literature, industry and from the lecturer's team. The stress was put on control methodologies and their
performance. Vector and direct active and reactive power control was given a special attention for fast and robust sensorless control with four quadrant PWM and 100% active and reactive power delivery converters. Lively discussion with
over 30 participants during and after presentation has proved importance of this topic.
