摘要

This paper is focused on the position and attitude control of spacecraft with multiple liquid propellant tanks, while considering large amplitude propellant slosh and depletion. The large amplitude liquid slosh is included by using a moving pulsating ball model that is further improved by taking mass varying liquid propellant into account. A hybrid controller that combines sliding mode control with an adaptive algorithm is designed for spacecraft to perform position and large angle maneuvers, and the proposed controller is proved to be asymptotically stable. Numerical simulation results are presented to verify the effectiveness of the control approach when the spacecraft undergoes the disturbance of large amplitude slosh and liquid propellant depleting. Moreover, the influence of propellant depletion on maneuver completion time is also investigated. Finally, the designed adaptive algorithm is validated to be effective to reduce the maneuver completion time and the sensitivity of the controller on the mass varying propellant.
