Implementación de un Control Activo de Ruido en Configuración Feedback basado en un Microcontrolador
2018
This work describes an active noise control system implementation with reduced, low cost hardware using the EDU-CIAA-NXP board. 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.
