3D Modeling and nonlinear Control of a Satellite with 3D Fuel Slosh Dynamics, M.Sc. Thesis Sharif University of Technology ; Fathi, Mohsen (Supervisor)
Abstract
The thrust vector control problem is studied for a Satellite with fuel slosh dynamics. The sloshing propellant is modeled as a 3D pendulum. The coupled equations of motion of the satellite and the fuel are expressed in terms of the three dimensional satellite translational velocity vector, the attitude, the angular velocity, and the internal coordinates representing the slosh modes. A nonlinear feedback control law with the idea of backstepping integrator is proposed to control the translational velocity vector and the attitude of the satellite, while attenuating the sloshing modes. A simulation example is included to illustrate the effectiveness of the control law
