Abstract :
A difficult and well-known problem for adaptive noise cancellation arises when there are plant resonances blocking the noise cancellation path. A new algorithm is proposed for this problem based on a modification of the augmented error algorithm of Monopoli (1974). It is shown using a recently developed LTI analysis framework that the modified algorithm has several performance and robustness advantages over both the filtered-X and augmented error algorithms for this class of problems
