摘要

Thin-walled flexible workpieces are known to be the most commonly used flexible elements in mechanical structures and machines in the industries of aerospace, national defense, petrochemistry, and so on. Workpiece machining vibrations induced by machining tools greatly worsen the efficiency and accuracy of milling processes, and hence, vibration attenuation has become a bottleneck for improving the machining quality of thin-walled flexible workpieces. An active vibration control system is hereby established to attenuate vibration by using laser displacement detectors and voice coil motors (VCMs). In this paper, we reveal that the vibration attenuation problem can be theoretically formulated as an output regulation problem subject to saturated actuation of VCMs. Within the formulation, a saturated output regulation algorithm is successfully implemented and its effectiveness is extensively examined by experiments.
