Abstract

In this paper, the feasibility of an active vibration control scheme using Fiber Bragg Grating (FBG) sensors and piezoelectric (PZT) actuators for vibration suppression of an aluminum plate is investigated. Four FBGs have been bonded to the structure below the same number of PZT actuators in co-located configuration. A Proportional-Derivative controller has been used to generate the command signals required to drive the actuators. Preliminary results from "closed loop" configuration tests are reported showing up to 17 dB of noise reduction at 80 Hz.
