Improvement of Convergence Speed for Active Noise Control Using the Simultaneous Perturbation Method
Yukinobu Tokoro, Yoshinobu Kajikawa, Yasuo Nomura (Kansai Univ.)
Abstract (in Japanese) (See Japanese page) 
(in English) Active noise control (ANC) system using the simultaneous perturbation method has an excellent feature that the excited noise can be controlled even if the control point is moved, because the secondary path model is unnecessary. However, the conventional perturbation method has a problem that the convergence speed slows as the frequency of noise becomes high. In addition, when the frequency characteristic of the secondary path has dips, the cancellation performance deteriorates since it is not be able to control perturbation magnitude well. Therefore, we propose an updating algorithm considering the frequency characteristic of secondary path and a frequency domain variable perturbation control method. The effectiveness of the proposed methods is demonstrated through simulation results.
