Design of Active Noise Control Systems Operating in Three-Dimensional Nondispersive Propagation Medium

摘要

A coherent method for the design of active noise control (ANC)systems operating in a three-dimensional non-dispersive propagation medium (acoustic free field) is presented. An analysis of the basic control structures is provided and conditions for the robust operation of such systems are determined. Finally, these conditions are interpreted as constraints on the geometric compositions of the ANC system.
