Prof. André Preumont,
head of The Department of Mechanical Engineering and Robotics -
Active Structures Laboratory (ASL) at the Université Libre de Bruxelles organizes
in collaboration with Micromega Dynamics, a short course on:
ACTIVE VIBRATION CONTROL
DATE
May 17-19, 2006
LOCATION
Wallonia Space Logistics (WSL)
Liege Science Park
Rue des Chasseurs Ardennais
ANGLEUR, BELGIUM
SCOPE
This introductory course is targeted at structural engineers in industry and
universities willing to acquire some background in active vibration control. The
course may also be useful to people involved in the modeling of smart structures
and to control engineers willing to understand the key issues in structural
control and piezoelectric transduction mechanisms. The applications covered during the course belong to aerospace and
civil engineering, transportation and vibroacoustics.
The lectures are based
on two books:
VIBRATION CONTROL OF ACTIVE STRUCTURES, 2nd edition, AN INTRODUCTION.
KLUWER 2002
MECHATRONICS: Dynamics
of Electromechanical and Piezoelectric Systems, Springer
2006
In order to insist on the practical aspects of the problem, the course is
illustrated with examples which are
analyzed in detail from the point of vue of modeling, control,
hardware, instrumentation, and technology.
Covered Topics
- Structural dynamics
- Smart materials
- Actuation and sensing
- Finite element modeling
- Collocated/non-collocated control
- Active damping
- Vibration isolation
- Semi-active control
- Controllability
- Stability
- Robustness
- Frequency shaping
- Applications

Accommodations
The two following hotels offer
preferential rates for this event:
Hotel Mercure - Liège
Hotel Holiday Inn - Liège
(click on a hotel name to download a reservation
form)
Please beware that hotels
in Liège will be rather crowded as there are
several events organized concurrently at that
time of the year. This will be particularly the
case on May 17, 2006. We recommend to place
reservations well in advance. This is also the
reason why hotels adopt a quite stringent
cancellation policy.
