An adaptive feedback control system (7) has a feedback loop (8) and a digital adaptive compensation filter (10). An auxiliary noise signal (30) is added to a reference signal (26) for use in residual-loop gain identification. A residual-loop gain identifier uses the noise signal (30) and a signal taken...http://www.google.fr/patents/US6665410?utm_source=gb-gplus-shareBrevet US6665410 - Adaptive feedback controller with open-loop transfer function reference suited for applications such as active noise control
