Abstract
An active control approach that reduces transient noise transmission t hrough a membrane in a circular duct is presented. Discrete sections o f piezo-electrical film, PVDF, are used os actuators to adjust the ten sion of the membrane. Different control strategies, such as optimal, s liding mode and velocity feedback control, are investigated analytical ly and then implemented experimentally. It is shown that velocity feed back control is the more effective, stable controller for this applica tion.
