L'avènement des opérations en orbite, telles que l'assemblage et la maintenance de satellites, ouvre de nouvelles perspectives pour l'exploration spatiale en réduisant les coûts de lancement et en offrant une plus grande flexibilité. Cependant, ces opérations complexes nécessitent le développement de systèmes robotiques capables de fonctionner dans un environnement hostile et de réaliser des tâches de haute précision. Les applications potentielles sont nombreuses, allant de la construction de stations spatiales ...

Most attitude control scenarios are highly affected by fuel slosh dynamics that must be carefully taken into account to preserve pointing accuracy. Since such dynamics are not easily predictable, standard strategies consist of bounding the performances of the control system to avoid interactions between the rigid dynamics of the spacecraft and the oscillating liquid motion inside the fuel tank. Thanks to a recently developed control-oriented CFD-based fuel slosh model, alternative ...

The COMET-SCA and the GT MOSAR (Methods and Tools for robust control and analysis) from GDR MACS co-organize a workshop on Robust Control and Convex Optimization. The objective of the workshop is to assess the theoretical and numerical issues of robust control and analysis methods. The upsides and limitations of these methods will be illustrated through application examples in space domain. This workshop is a great opportunity to meet the experts on ...

  The topic of the seminar was the current and past studies on modelling and control of sloshing modes with a focus on recent theses results. Past and forthcoming demonstrators has been presented including the FLUIDICS experiment which has flown on the ISS in 2017.

Seminar on Drag Free Missions MICROSCOPE and LISA PATHFINDER: lessons learned The workshop was dedicated to the main issues of both missions Microscope and Lisa Pathfinder and allowed participants to get an idea of ​​the difficulties encountered and the lessons learned from both flights.  Each session was organized as follows : 30 min Microscope lecture, 30 min Lisa PathFinder lecture, 30 min of free exchange. Agenda Wed Sept 6th 09:00-10:30 Presentation of the missions (objectives, industrial organization, requirements) - ...
