Neste artigo, propomos um sistema de controle ativo de ruído (ANC) no domínio da frequência sem um modelo de caminho secundário. O sistema proposto é baseado no método de perturbação simultânea no domínio da frequência (FDSP) que propomos. Neste sistema, os coeficientes do filtro adaptativo são atualizados apenas por sinais de erro. O sistema ANC convencional que utiliza o algoritmo x filtrado torna-se instável devido ao erro entre o caminho secundário, da fonte secundária ao sensor de erro, e seu modelo. Em contrapartida, o sistema ANC proposto tem a vantagem de não utilizar o modelo. Neste artigo, mostramos o princípio do sistema ANC proposto e examinamos sua eficiência através de simulações computacionais.

Abstract: In this paper, we propose a frequency domain active noise control (ANC) system without a secondary path model. The proposed system is based on the frequency domain simultaneous perturbation (FDSP) method we have proposed. In this system, the coefficients of the adaptive filter are updated only by error signals. The conventional ANC system using the filtered-x algorithm becomes unstable due to the error between the secondary path, from secondary source to error sensor, and its model. In contrast, the proposed ANC system has the advantage not to use the model. In this paper, we show the principle of the proposed ANC system, and examine its efficiency through computer simulations.
