Damping Position-dependent Parasitic Vibrations

Year: 2024

Type: article

Abstract: Parasitic resonances are often limiting the performance of precision machinery. The associated resonance frequency and mode shape may change over the workspace of the machine, making robust suppression or damping of these parasitic resonances a non-trivial task. This article outlines an active damping method for the suppression of position-dependent parasitic resonances through small integrated piezoelectric sensors and actuators, and shows its application to a flexure mechanism. Applying a resonant control technique, the limited actuation budget is efficiently used. A scheduling approach is followed to deal with the position-dependent behaviour. This leads to a significant improvement of the disturbance sensitivity of the flexure-based manipulator.
