Regenerative Power-Optimal Reaction Wheel Attitude Control

摘要: This paper develops an analytical instantaneous power-optimal attitude control for a spacecraft using integrated reaction wheel–flywheel system allowing energy storage and return. The is formulated in general manner to use arbitrarily large number of wheels. It applicable systems with redundant wheels spanning three-dimensional space, which are controlled by law. power usage minimized modifying the wheel torques torque null motion. In this study, reducing speed results negative perfect recuperation. Applying maximum available constraints, solution space reduced hyperdimensional vector geometry problem, uniquely determined. modifications applied both regulation tracking laws, demonstrating its performance variety initial states. Not only does new maximize extraction from wheels, it also maintains smallest flywheel spin rates, helps reduce maneuver-wide usage.
