The filtered-X LMS algorithm is described in its feedforward and feedback configurations, and design details for anti-alias and reconstruction filters are given. The software driving the system is described and test results in feedforward configuration are shown. Using a pure tone as the perturbing signal, a 30dB attenuation was achieved, which is adequate according to performance requirements in active noise control applications. Este trabajo describe la implementación de un sistema de control activo de ruido sobre la plataforma EDU-CIAA-NXP con hardware reducido y de bajo costo. Se hace una revisión del algoritmo filtered-X LMS en configuraciones feedforward y feedback, y se detalla el diseño de filtros anti-alias y de reconstrucción. Se describe el software que corre sobre la plataforma, y se muestran resultados de ensayos con la configuración feedback. Usando un tono puro como señal perturbadora se logró una atenuación de 30dB, que es adecuada según requerimientos de performance en aplicaciones de control activo de ruido. application/pdf application/pdf application/pdf text/html https://elektron.fi.uba.ar/elektron/article/view/49 10.37537/rev.elektron.2.2.49.2018 spa eng FIUBA https://elektron.fi.uba.ar/elektron/article/view/49/43 https://elektron.fi.uba.ar/elektron/article/view/49/416 https://elektron.fi.uba.ar/elektron/article/view/49/417 https://elektron.fi.uba.ar/elektron/article/view/49/136 Derechos de autor 2018 Pablo Gomez Elektron Journal; Vol. 2 No. 2 (2018); 53-62 Revista Elektron; Vol. 2 Núm. 2 (2018); 53-62 Revista Elektron; v. 2 n. 2 (2018); 53-62 2525-0159 2525-0159 acoustics audio control filtered-X LMS EDU-CIAA-NXP acústica audio control filtered-X LMS EDU-CIAA-NXP Microcontroller-based Feedback Active Noise Control Implementación de un Control Activo de Ruido en Configuración Feedback basado en un Microcontrolador info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://repositoriouba.sisbi.uba.ar/gsdl/cgi-bin/library.cgi?a=d&c=elektron&d=49_oai
