Abstract
This paper evaluates spacecraft adaptive attitude control by examining the contributions of individual components of one common adaptive algorithm. Feedforward and feedback controls are briefly introduced for context, then parameter adaptation and reference trajectories are applied individually to feedforward and feedback controls. The effects of noise are also examined. The various control schemes are simulated to heuristically display the impacts of reference trajectories versus desired trajectories, adaptation versus non- adaptive, and also the effects of adaptation and control gains in addition to sensor noise. The simulations are validated by experimental results on a free-floating three-axis spacecraft simulator actuated by non- redundant single-gimbal control moment gyroscopes.
