Abstract
An adaptive control system that can be used for active acoustic attenuation implements an LMS or an RLMS update using an error signal that is filtered through a delayed Hermitian transpose of a C model of an auxiliary path following an adaptive control filter. Adaptive on-line C modeling can be used effectively. The invention is useful in SISO and MIMO applications, and can reduce the number of filtering operations in systems using several reference signals. The invention does not require inverse C modeling.
