Title:
【発明の名称】閉ループ制御システムにおける適応形雑音消去
Document Type and Number:
Japanese Patent JP3056492
Kind Code:
B2
Abstract:
An adaptive noise cancellation system reduces undesired noise in a closed loop control system by injecting an adaptively constructed noise cancellation signal at an appropriate point in the closed control loop. The generation of a compensation filter N for adaptive noise cancellation loop error signal is disclosed by two methods. A first method is an inverse error rejection response (IERR) method. A second method optimally matches spectrums of a noise signal and a noise reference signal at the adaptive noise cancellation system. This second method is referred to as a spectral matching (SM) method.
