Standard radiator areas for Earth orbiting spacecraft have surface finishes with high emissivity and typically low solar absorptivity. This guarantees low temperatures even with the sun shining on these surfaces. The environmental conditions for Merc

Linear closed loop systems are usually tested for robustness with respect to uncertain parameters using an upper Linear Fractional Transformation (LFT). This paper presents a method to calculate such a LFT for a system with a very large number (more

In this paper, the general formulation of periodically time-varying state-feedback controllers with memory is considered for the first time. New analysis and synthesis conditions for robust stability are proposed. The flexibility of these new results

International audience; Particularly attractive for small satellites, the use of magnetic torquers for attitude control is still a difficult problem. Indeed, equations are naturally time-varying and suffers from controllability issues. In this paper,
