International audience; Because satellites usually do not experience large changes of mass, center of gravity or inertia in orbit, linear time invariant (LTI) controllers have been widely used to control their attitude. But, as the pointing requireme

SUMMARY This paper introduces a method for designing structured adaptive laws for ‘almost stable’ systems (systems for which a static output feedback gain is known). Structuring the adaptation law allows the designer to specify different evolutio

This paper considers the problem of reaction-wheel attitude control inside the mission mode of the Myriade satellites. A structured adaptive algorithm, allowing to extend the operating domain of a static proportional- derivative controller is present

International audience; Numerical problems such as finding eigenvalues, singular value decomposition, linear programming, are traditionally solved with algorithms that can be interpreted as discrete-time processes. One can also find in the literature

This paper studies time-varying structures for satellite attitude control systems. The considered satellites are from the Myriade family developed by the French Space Agency (CNES). Analysis of the existing control law and control requirements show t
