Spacecrafts
Control systems are an essential part of every space system and are necessary to successfully fulfill the mission objectives. These include the successful launch and landing of a launch vehicle, the precise orientation of satellites for measurement and communication as well as the navigation and stability of landers. Exact non-linear models of the systems and environment are an important basis for control design and performance evaluation. The constantly growing industrial interest in space applications creates the basis for many exciting theses in this field of reseach.

Motivation:
The sloshing behavior in the main tanks of a liquid rocket has a significant influence on its flight dynamics and can lead to the loss of the rocket in extreme cases. It is therefore important that these effects are taken into account when designing the controller for a rocket in order to guarantee the success of the mission. As part of this research project, an already non-linear simulation environment of the chair is to be expanded to include sloshing dynamics.
Task definition:
-
Literature research on the modeling of fuel sloshing at different mission times (launch, stage separation, landing)
-
Literature research on active/passive damping methods and their modeling
-
Derivation of a model for propellant sloshing in the main tanks of a liquid rocket for v
-
Implementation in a non-linear simulation environment in Matlab/Simulink
-
Design of a controller for active damping of the propellant slosh
-
Verification through reference missions
