A Generic Active Vibration Control System of Surfaces

Objective



The main objective of this Basic Research project is to
develop a self contained, "black box" type Active
Vibration Control System (AVCS) for the vibration
control of flexible, vibrating surfaces. This is
envisaged to be achieved through the use of a "smart"
surface consisting of a number of layers actuator/sensor
type material, such as piezoceramic films, polyvinylene
fluoride films, electromechanically treated films, etc.,
coupled to a power supply and a controller which contains
all the controlling software that make the AVCS a self
contained, "black box" type product.

The important benefits/characteristics of such an AVCS
are the following.
1. It is independent of the shape of the "flat" surface
of which the vibrational control is desired.
2 It does not require any analysis, e.g., Finite Element,
or experimental measurements of the vibrating surface.

3. It does not require any analysis or experimental
measurements of thc "smart" surface attached to the
vibrating surface.
4. It does not require any knowledge of vibration
analysis and control by the user. Only a technician is
required to know how to apply and make the connections
to the power supply and the controller (In industrial
application it is envisaged that all the algorithms of
the controller will be provided in a mass produced
microchip).
All the above benefits/characteristics truly characterise
the proposed "smart" surface AVCS as a Generic one. In
the present project a prototype "smart" surface will be
developed/constructed (its optimization will be the
subject of future industrial research). The frequency
analysis, the expert system, Artificial Neural Network
(ANN) and genene algorithms (GA) will be developed. An
integrated AVCS will be constructed. The "smart" surface
will be attached to representative vibrating flat
surfaces and laboratory tests will be performed to
demonstrate its performance characteristics.
