Abstract
One of the reasons for actively controlling the vibration of a structure may be to reduce its sound radiation. Before considering such active vibroacoustic 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 available in some applications and this allows feedforward control systems to be implemented, which do not suffer from the limitations of the Bode sensitivity integral in the same way that feedback control systems do. In order to be robust to changes in the disturbance and plant such feedforward controllers are often made adaptive and are also widely used to control tonal acoustic disturbances, in particular those experienced in the passenger cabins of propeller aircraft, with typical commercial systems having 36 loudspeakers and 72 microphones.
