Comments on the Convex Constrained Spacecraft Reorientation

We investigate a class of Lyapunov-based attitude control algorithms dedicated to keep-out zone avoidance. They utilize convex representations of the allowed attitude and potential barriers that are also supposed to be convex. We show that such parameterization is not actually convex, and that sugge...

Description
Summary:We investigate a class of Lyapunov-based attitude control algorithms dedicated to keep-out zone avoidance. They utilize convex representations of the allowed attitude and potential barriers that are also supposed to be convex. We show that such parameterization is not actually convex, and that suggested control generates additional asymptotically stable equilibria.
