In this paper, a
nonlinear robust quaternion-based controller is developed to address the
three-axis attitude tracking control problem of rigid spacecraft in presence of
parametric uncertainties, unknown external disturbances and sensor noise. As a
first step, a robust controller is designed that compensates parametric
uncertainty and disturbance effects. The robust controller then reformulated to
deal also with sensor noise. Singularity free unit quaternions are used to
represent the attitude of the satellite in three-dimensional space. The
Lyapunov-based stability analysis is applied to prove that a uniformly
ultimately bounded tracking result is achieved. Simulation results are
presented to illustrate the feasibility of the proposed control strategy.
