Modelización, Análisis y Control de Sistemas de Cojinetes Magnéticos Activos

I. Arredondo, J. Jugo, S. Alonso-Quesada, I. Lizarraga, V. Etxebarria


En este estudio se presentan el modelado, diseño de control, análisis de robustez y procedimiento de reducción activa de vibraciones de un sistema consistente en un eje sustentado mediante levitación magnética activa. Primero se describen la obtención del modelo y las características fundamentales del sistema. Empleando dicho modelo y aprovechando propiedades de simetría, se diseña un control de sustentación. Este se ajusta experimentalmente mediante un estudio de robustez, según el estándar ISO 14839-3. Por último, se realiza una reducción de las vibraciones que se producen en rotación, utilizando control adaptativo. El controlador final diseñado ha sido implementado experimentalmente con éxito.
