Abstract:

In this paper we propose an approach to apply a recently developed extended H? controller that accounts for actuator saturation in the design phase. We apply this controller to a satellite with large flexible appendages, actuated with Reaction Wheels Assembly. We augment the controller with a feedback linearization contribution to compensate for nonlinear terms due to the coupling of attitude dynamics and actuation.
