Effect of Reaction Wheel Imbalances on Attitude and Stabilization Accuracy

et al. 2021

In this paper, the study of stabilization accuracy of a satellite equipped with a set of reaction wheels (RW) is presented. The model of motion takes into account possible static and dynamic reaction wheel imbalances. Due to the complexity of the model, which leads to the numerical issues, the effects of dynamic and static imbalances on inertial stabilization are studied analytically. As a result, estimations of the attitude and stabilization accuracy are presented in closed form.

“…As one can see, both dynamic and static imbalances lead to the additional terms in the right parts of Equations ( 15) and (20), which do not depend on satellite state vector components for the first order approximation, so the total stabilization accuracy is the sum of Equations ( 17) and (21). )…”
