[Abstract]:Firstly, the research status of rigid-liquid coupling dynamics modeling of liquid-filled spacecraft is introduced, and the modeling method of equivalent shaking dynamics model widely used at present is introduced. Secondly, the selection of different actuators is discussed. Based on Lyapunov stability principle, sliding mode control, adaptive feedback control and other liquid-filled spacecraft control liquid fuel sloshing and attitude control schemes are summarized and analyzed. Finally, In this paper, the attitude control of liquid filled spacecraft is summarized, and the future research direction of liquid filled spacecraft is prospected.
