Modeling and control of an ultra-fine accelerometer

报告内容

摘 要

Numerous space applications such as the fundamental physics experiments mission LISA,GP-B, MICROSCOPE and earth’s gravity observation mission CHAMP,GRACE,GOCE require dedicated accelerometers with ranges and sensibilities optimized for the in-orbit environment. In fact, electrostatically levitated accelerometers have been utilized in space for extremely high sensitivity.  This accelerometer can’t work on ground because of gravity acceleration g. in our lab, high-voltage levitation, pendulum and drop dower have been used to provide micro-gravity on earth to test accelerometer. To improvement the experiment, it is necessary to modify the modeling of accelerometer and also the control. I will introduce some work about modeling and control design of accelerometer.

简 介

Enrico Canuto received his degree in Electrical Engineering from Politecnico di Torino,Turin,Italy, where he joined the staff as a Professor of Automatic Control in 1983.

Since 1998 he conceived and developed a model-based design and implementation methodology for digital control and automation (Embedded Model Control), tested on industrial controllers. For this reason, Thales Alenia Space Italia granted Politecnico di Torino in 2001 with the design of the drag-free and attitude control of the GOCE satellite during the scientific phase.

Current studies on the Next Generation Gravity Missions  (NGGM) based on long-distance satellite formation and laser interferometry.
