Abstract

This paper presents an overview of the control analysis activity related to the development of figure control technologies for large space telescopes with precision segmented, actively controlled, primary reflectors. The issues addressed here involve the development of geometric and dynamic models, characterization of figure estimation errors and optimal sensor placement, and the development of quasi-static and dynamic control concepts. The most significant simulation results obtained during an extensive performance evaluation are also presented.
