Signal Processing for Active Control

von Stephen Elliott Kategorie: Akustik ISBN: 0122370856 Kommentar abgeben

Kurzbeschreibung The active control of sound and vibration is a current and technologically important problem. It involves the introduction of controllable secondary sources of sound or vibration, which act to suppress the original primary disturbance. The effects of the secondary sources are superimposed on the primary sources.

Signal Processing for Active Control sets out the signal processing and automatic control techniques that are used in the analysis and implementation of active systems for the control of sound and vibration. Stephen Elliott briefly reviews the performance limitations introduced by physical aspects of active control, then presents the calculation of the optimal performance and the implementation of real time controllers for a wide variety of different active control systems. Practical applications are presented at the end of each chapter to illustrate the use of various approaches.
