In this paper, we consider thc problem of three-axis robust attitude stabilization of a rigid spacecraft using minimal, three-dimensional kinematic parameters. New nonlinear control laws having a class of relaxed feedback gain structures are proposed, and are shown to provide a robustness with respect to inertia uncertainties of a rigid body. A numerical example is given to illustrate the theoretical results.
