Paper Abstract

In designing a controller, one way to avoid energy spillover is to use what is called the zero spillover control scheme. Here, this scheme is studied for actively controlling sound fields inside an enclosure with a flexible boundary. Noise is transmitted into the enclosure through the flexible boundary, and piezoceramic patches, which are mounted on the flexible boundary, are used as actuators. Polyvinylidene fluoride sensors are used on the flexible boundary and microphone sensors are used inside and outside the enclosure. The locations of the sensors needed to construct a zero spillover controller are discussed along with other issues.
