Resumen
Basados en modelos y datos experimentales previos, se presenta un esquema feedback–feedforward aplicado al control activo de ruido acústico en cascos de motociclistas. La estructura es la del control de 2 grados de libertad tomando información de una señal proporcional al ruido externo al casco y del ruido efectivo en el oído del motociclista. Se comparan diseños realizados mediante la parametrización de Youla, el control óptimo en H∞ y la síntesis–μ (diseño por valor singular estructurado). Se realiza un análisis en términos del desempeño, robustez y el orden de los controles resultantes.
Palabras clave:
