Active damping in precision equipment

Description of research

Active damping in precision equipment. Specifically, we address the so-called rocking mode, which is a vibration mode that presents itself in machines having linear actuation, due to finite rotational stiffnesses of linear guidances. Goal of the research is to overcome the limitation that this vibration mode imposes on the machine precision and closed-loop bandwidth by means of active damping units. An active damping unit is a device that can be built into the machine at appropriate locations and that incorporates a piezo force sensor, a piezo position actuator and a controller that realizes damping.
