Abstract

The requirements concerning satellite optical instruments pointing stability are getting more and more stringent. To put up with a disturbed dynamic environment, the Line-of-Sight (LOS) control laws have to be efficient over a large bandwidth. One of the main performance limitation comes from the flexible modes of these optical payloads and their variations w.r.t host satellite configuration. To solve this problem, both classical frequency domain and modern H2/H1 syntheses have been performed and validated on the CAT experimental test facility (CAT: Contrôle d’Attitude de Télescope).
