Abstract :
A Lyapunov-based adaptive controller is proposed to perform on-orbit stabilization for spacecraft attitude control systems (ACS). The stability of the adaptive controller is guaranteed by minimizing the Lyapunov function of the error derived from the direct adaptive model-following scheme. A complete formulation of the adaptive controller scheme wherein various feedback stabilization techniques are examined is presented. Its robust performance when subjected to mass properties changes is verified by simulation
