This work explores a novel efficient and low-cost control scheme for rigid spacecraft attitude stabiliza-tion problem, in which the unavailability of angular velocity measurements is considered. The resulting controller is independent on spacecraft inertia parameters, and explicit accounts for control input saturation with angular velocity measurements eliminated. Moreover, the proposed control law allows L2 gain of the closed-loop attitude system to be chosen arbitrarily small so as to achieve any level of L2 disturbance attenuation. Numerical simulation results are also presented to highlight those highly desirable features.
