Systematic design methods of robust and structured controllers for satellites. Application to the refinement of Rosetta's orbit controller

Falcoz, Alexandre; Pittet, Christelle; Bennani, Samir +3 more

In this paper, the capability of nonsmooth optimisation techniques to solve complex control problems with implementation issues is addressed. {H}_{∞}/ µ design methods are analysed to enhance the current Airbus Defence and Space industrial development process. In the first instance, a reference µ-synthesis controller that achieves the …

ESA multibody simulator for spacecrafts' ascent and landing in a microgravity environment

Toso, Mario; Pennestrì, Ettore; Rossi, Valerio

The investigation of planets, moons and small bodies, including comets and asteroids can contribute substantially to our understanding of the formation and history of the solar system. In situ observations by landers play an important role in this field: for example, the Rosetta Lander Philae has been the first spacecraft to accomplish a soft touc…
