Abstract:
This paper proposed rapid development of an air bearing three-axis stabilized satellite system. In order to facilitate the centroid adjustment and instrument assembling, a symmetrical structural platform is designed. Taking into account the payload and motion range, the super-hemispherical air bearing is designed. The three orthogonal flywheel modules have been developed for attitude control. Regarding the fast centroid adjustment, the three orthogonal screw mass adjustment mechanism is designed, and the adjustment method is given to realize the requirement of gravity eccentric interference torque less than 0.01Nm. Finally, the PD control law is tuned to realize the three-axis attitude stability control, and the control accuracy is 0.5°.
