Modale Regelung von Werkzeugmaschinen

Feed axes of machine tools are often equipped with several parallel acting drives. Additional actuators for active vibration damping are also increasingly used. This article introduces the modal control for machine tools. The modal approach enables the eigenmodes to be controlled independently and the excited vibrations to be damped specifically with all available actuators. The results for the modal control of a gantry arrangement are presented as an example.
