Abstract
Piezoceramic actuator placement is investigated to minimize structurally radiated noise of flat and curved panels subjected to a uniform random acoustic disturbance. The flat panels use traditional PZT actuators, while the curved panels incorporate anisotropic macro fiber composite (MFC) PZT actuators. A linear quadratic regulator (LQR) feedback control augmented with acoustic radiation filters is used to minimize the radiated noise. A coupled finite element model is used in conjunction with a genetic algorithm to determine the optimum actuator location for two PZT actuators. Experiments are conducted to verify analytical simulation results.
