摘要

In designing a controller, one way to avoid energy spillover is to use what is called the zero spillover control scheme. Here, the feasibility of this scheme is studied experimentally 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. For narrowband disturbances, attenuation ranging up to 17.0 dB has been realized. Controller stability and robustness of zero spillover controller are discussed along with other issues.
