Vibration control of flexible structures using fusion of inertial sensors and hyper-stable actuator-sensor pairs

摘要

This paper discusses sensor fusion techniques that can be used to increase the control bandwidth and stabilityudof active vibration isolation systems. For this, a low noise inertial instrument dominates the fusion at lowudfrequency to provide vibration isolation. Other types of sensors (relative motion, smaller but noisier inertial,udor force sensors) are used at higher frequencies to increase stability. Several sensor fusion configurations areudstudied. The paper shows the improvement that can be expected for several case studies.
