Abstract

Linear transfer function models based on frequency response identification techniques are developed to describe the flexural vibration of a cantilever beam when excited using piezoceramic patches bonded to a constrained layer damping treatment. Predictions of dynamic behavior, obtained using the models, are validated by comparison with results from laboratory experiments. The models are then used in open loop and closed loop velocity feedback control simulations to demonstrate the improvements in stability and performance.
