Abstract

SE EXPONE UN SISTEMA DE CONTROL ACTIVO DEL RUIDO (O VIBRACIONES) QUE TIENE UN ACCIONADOR (24) QUE PROPORCIONA UNA SEÑAL ACUSTICA ANTIRRUIDO, EN RESPUESTA A UNA SEÑAL DE ACCIONAMIENTO (U), UN SENSOR DE ERROR (16), QUE DETECTA LA SEÑAL ACUSTICA ANTIRRUIDO DEL ACCIONADOR, DETECTA EL RUIDO PERTURBADOR (D) Y PROPORCIONA UNA SEÑAL DE ERROR (E) QUE INDICA UNA COMBINACION DE LAS MISMAS, Y UN CONTROLADOR (20), QUE RESPONDE A LA SEÑAL DE ERROR (E), QUE PROPORCIONA AL ACCIONADOR (24) LA SEÑAL DE ACCIONAMIENTO (1), TENIENDO COMPENSACION (78) DEL CONTROLADOR CON ESTADOS DE ENERGIA (112) Y UNA LOGICA (130) DE REPOSICION NO LINEAL, QUE REPONE TEMPORALMENTE A CERO LOS ESTADOS DE ENERGIA (112) DEL FILTRO (78) CUANDO LA SEÑAL DE ERROR CRUZA EL CERO, MEJORANDO DE ESE MODO LA ANCHURA DE BANDA DEL SISTEMA DE CONTROL ACTIVO DEL RUIDO.
