Abstract

This paper presents experimental results on the active structural acoustic control of a new smart panel with sixteen triangularly shaped piezoelectric patch actuators, whose base edges are evenly distributed along the perimeter of the panel. Accelerometer sensors are placed at tip of the actuators in order to implement decentralized Direct Velocity Feedback (DVFB) control loops. DVFB control system generates active damping, which reduces hybrid controller adaptive, ideal performance and granted stability of the closed loop system can be achieved for both free and forced vibrations. The proposed controller remains effective for large variation in system parameters.
