Abstract

Este trabajo propone un control activo de vibraciones en un sistema mecánico tipo viga en voladizo, utilizando un controlador fuzzy implementado en LabVIEW. Para la etapa de medición se utiliza un acelerómetro capacitivo capaz de detectar el desplazamiento presentado en la estructura debido a una fuerza generada mediante un impactador instrumentado con un sensor piezorresistivo. Para la implementación computacional es utilizado el software LabVIEW operando en conjunto con una tarjeta de adquisición de datos DAQ 6009. Para el sistema de actuación se ubican en la barra láminas de material piezoeléctrico, que tienen la función de atenuar la vibración presente mediante la generación de fuerzas opuestas. Los resultados experimentales se presentan con el objetivo de acumular experiencias y demostrar la eficacia del control activo de vibraciones con la utilización de actuadores piezoeléctricos.
