An Introduction to Active Vibration Control,led “Terrestrial Planet Finder” aims at detecting earth-sized planets outside the solar system; other missions include the mapping of the sky with an accuracy one order better than that achieved by .).

Active Vibroacoustic Control,hat sound could be controlled using acoustic actuators such as loudspeakers, and in this chapter we will discuss how vibration actuators, acting directly on the structure, can be used to reduce its sound radiation. This may be termed active structural acoustic control or active vibroacoustic control.

PVDF-Transducers for Structural Health Monitoring,f the location and force-time-history by external sources, active sensing diagnostics of structures serves for localization and determining the magnitude of a damage. This paper shows the application of polyvinylidene fluoride (PVDF) sensors and actuators for its use in structural health monitoring.

Active Sound Control,ustic control systems in a later chapter, we use this chapter to review the physical limitations of purely acoustical active control systems, i.e. those in which a soundfield is controlled using acoustical sources. The nature of sound propagation also means that a time-advanced reference signal is a
