Abstract

UN SISTEMA DE CONTROL DE LA VIBRACION ACTIVA EN EL CUAL UN SENSOR DE ENTRADA (2) GENERA PRIMERAS SEÑALES REPRESENTATIVAS DE UN CAMPO DE VIBRACION PRIMARIA, ACTUADORES (1) QUE SON ACCIONADOS POR SEGUNDAS SEÑALES PARA PRODUCIR UN CAMPO DE VIBRACION SECUNDARIOS, SENSORES DE CONTROL (3) QUE PRODUCEN TERCERAS SEÑALES, ESTAN POSICIONADOS EN UNA PRIMERA REGION (4) DIFERENTE DE UNA SEGUNDA REGION DONDE LA VIBRACION ES CONTROLADA, UN CONTROLADOR (5) ES RESPONSABLE DE LAS PRIMERAS SEÑALES PARA GENERAR SEGUNDAS SEÑALES QUE REDUCEN LA VIBRACION EN LA SEGUNDA REGION, Y EL CONTROLADOR ES ADAPTABLE EN RELACION A LA PRIMERA Y TERCERA SEÑALES PARA MANTENER VIBRACION REDUCIDA EN LA SEGUNDA REGION.
