Effective Active Noise Control algorithm for gain and power constraints with limiting factor using adaptive filter

Abstract

In this paper, a new algorithm with multi constraints that can be used in active noise control is presented. This can be used to maintain the particular system power budget and prevent over driving. The filter used for the constraints is frequency domain of least mean square algorithm. A limiting factor is used in the algorithm to reduce the effect of the filter response at other frequencies. The algorithm can be either used in gain or output power constraint. The algorithm shows the better convergence rate than the existing algorithms. The finding of correct convergence point can be done through the secondary path.
