Vorschubachsen von Werkzeugmaschinen werden oft mit mehreren, parallel wirkenden Antrieben ausgestattet. Auch zusätzliche Aktoren für die aktive Schwingungsdämpfung kommen zunehmend zum Einsatz. Im Beitrag wird die modale Regelung für Werkzeugmaschinen vorgestellt. Sie ermöglicht es, die Eigenformen individuell zu regeln und die angeregten Schwingungen mit allen verfügbaren Aktoren gezielt zu bedämpfen. Es werden Ergebnisse zur modalen Regelung am Beispiel einer Gantry-Anordnung vorgestellt.   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.

Inertial Actuator

Self-sensing active vibration damping is advantageous if sensors cannot be placed collocated to actuators or these sensors add too much weight or cost. When self-sensing, electrodynamic actuators are used, damping is directly added to the structure where they are attached without the need of electronic integrators or differentiators that could destabilize the system. Inertial actuators have also the advantage that they do not need to react relative to a fixed ground. In this paper self-sensing control with a shunted resistor, current feedback, induced voltage feedback with and without inductance compensation are investigated in simulations and experiments. Experiments with a lightweight, inertial actuator on a clamped plate show that vibration amplitude is decreased between 6dB and 13dB and control bandwidth is doubled when the appropriate control scheme is used.
