In ANC system, it is possible for the systems to be unstable in the Filtered-X algorithm using RLS algorithm. This phenomenon comes from an error between the true value and an estimate value with an estimate which is caused by a change and an unsureness of the secondary path. Consequently, a Leaky RLS(LRLS) algorithm which let RLS stabilize has been proposed. Applying the leaky algorithms which improve stability to the Filtered-X algorithm yields good performance toward the estimated error of the secondary path. In this report, an influence on ANC systems by the estimation error of the secondary path and an application of a computationally efficient LRLS algorithm are analyzed through simulations on a computer. |
