2D Modeling and Fuzzy Control of Slosh Dynamics in a Spacecraft

Fuel slosh dynamics can disturb attitude of spacecraft which has a partially filled container, in orbital maneuvering. So, it is necessary to control this harmful phenomenon. This paper models coupled dynamics of fuel sloshing and attitude of the spacecraft by two-pendulum model, and designs a fuzzy controller to control sloshing and attitude dynamics of the vehicle. Also, effectiveness of this controller is illustrated by conducted simulation.
