Abstract

The control of the flexural intensity in complex structure that originates from point of force is used for a piezoelectric patch actuator. It is experimentally validated by comparison with a classical acceleration control. The instantaneous intensity is completely taken into account in the control algorithm. High attenuation of the mean RMS acceleration downstream of the error sensor location can be achieved by controlling harmonic disturbance with a piezoelectric patch.
