Abstract
ANC system using Frequency Domain Simultaneous Perturbation (FDSP) method considering controlled band with automatic perturbation control is proposed. The proposed system with variable perturbation magnitude can converge faster than the conventional method with a fixed perturbation magnitude. In the proposed method, perturbation magnitude is set in proportional to the error signal. As a result, this system solves the instability problem caused by block processing and the problem that perturbation can become a noise after a convergence. In this paper, the effectiveness is demonstrated through simulations.
