摘要
Active Vibration Isolation Control (AVIC) can be used to reduce the transmissibility of external vibrations to internal vibrations. In this paper a proposal is made for integrating AVIC in a Coriolis Mass-Flow Meter (CMFM). Acceleration feedback, virtual mass and virtual skyhook damping are added to a passively suspended CMFM, resulting in a lowered suspension frequency. In addition, position feedback of the internal deformation is used to damp the internal mode. The controller design is based on a simplified model and is validated on an experimental setup. Results show that the sensitivity to external vibrations is reduced by 40 dB for the RMS measurement error. (C) 2014 Elsevier Ltd. All rights reserved.
