Abstract
Piezoelectric materials have been used as sensors and actuators in vibration control problems. Recently, piezoelectric transduction has also received great attention for vibration-based energy harvesting. This paper proposes the self-powered active vibration control of a multilayered structure with two piezoceramic layers for scavenging energy, one for sensing and another one for actuation. An electrical circuit that calculates the control signal based on the electrical output of the sensing piezoelectric layer and simultaneously has energy harvesting capabilities is presented. The actuation energy is supplied by the harvested energy, which also powers active elements of the circuit. The performance of the self-powered active flutter controller is discussed.
