Piezeletric Actuators Placement Study Through Singular Analysis Value On The Cantilever Plate.

Abstract

The piezoelectric actuator and sensor, have received lot of attention by researcher.
The reason for this, it is because these devices present the piezoelectricity effect. This effect is
the conversion between mechanical energy in electric energy and vice versa. So this effect is
very useful in active vibration control, AVC, and its results are more effective than passive
vibration control. The intelligent structures are the units compound by: actuator, sensor,
controller and structures (Lima Jr, 1999). Intelligent structure good design, the actuators and
sensors placement are a fundamental part, because misplacement can cause lack of system
controllability and observability. So this paper intends to propose actuators placement
technique, through index obtained from singular value decomposition of control matrix [B].
The structure about the study is a cantilever plate and the results check with the simulation
done in finite elements.
