LPV Control for Multi-harmonic Microvibration Attenuation: Application to High Stability Space Missions

This paper presents a LPV (Linear Parameter Varying) solution for the active part of a mixed passive-active control architecture to mitigate the microvibrations generated by reaction wheels in satellites. H∞/LPV theroy is used to mitigate low frequency disturbances. The issue of multiple harmonic microvibrations is also investigated. The results are evaluated using H∞ criteria and simulation results from a test benchmark provided by Airbus Defence and Space demonstrate the potential of the proposed method.
