System identification for attitude control of satellites

Présentation PosterInternational audienceHigh fidelity satellite simulators are required for the validation of attitude control algorithms. For these simulators accurate and reliable satellite and orbital environment models are necessary. However, some parameters cannot be easily identified on ground (disturbing torques, satellites inertia, flexible modes characteristics, ...) and identification methods must be used during the satellite operation. This poster provides an overview on this topic and invites the workshop attendants for a discussion regarding which identification strategies may improve the estimate of the desired parameters with respect to the current solutions adopted. Starting from the problem definition, the system dynamics are described together with the limitation of the measurements; the main research challenges are highlighted. Finally, the poster ends with a couple of identification strategies that may be viable for the actual problem solution
