Effect of Reaction Wheel Imbalances on Attitude and Stabilization Accuracy

Effect of Reaction Wheel Imbalances on Attitude and Stabilization Accuracy

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 effec...

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.https://www.mdpi.com/2226-4310/8/9/252reaction wheelsimbalanceattitude accuracy
