Abstract :
The attitude tracking problem of uncertain rigid spacecraft without angular velocity measurements is addressed in the paper. The adaptive control law, which incorporates a velocity-generating filter from attitude measurements, is shown to ensure the asymptotic convergence of the attitude and angular velocity tracking errors despite unknown spacecraft inertia. Simulation results are presented to illustrate the theoretical results
