Job Description

Thesis title:

Reduced-order models (ROM) based closed-loop control for spacecraft fuel sloshing applications

Are you looking for a final year project? Would you like to discover the work of an engineer  Then apply now! We look forward to you joining usThe AOCS, GNC & FD department is in charge of attitude and orbit control systems (AOCS), Guidance/Navigation/Control (GNC), flight dynamics (FD), and control engineering for all kinds of spacecraft. Fuel sloshing is an important aspect in the frame of dynamics plant modeling.

Location: Friedrichshafen

Start: March / April

Thesis topic:

Fuel sloshing dynamics for spacecraft applications are typically represented by two extreme end modelling approaches, either by detailed coupled CFM/FEM or by extremely simplified mass-spring-damper / pendulum models. Both approaches can be justified, however they are not suited for general automatic control design purposes. Reduced-order models (ROM) offer an opportunity to bridge this gap. Moreover, they appear to be particularly suited to represent potential sloshing / structure interactions.

As a thesis student you will learn about:

Sloshing and flexible modes modeling for spacecraft, spacecraft control design, and verification

Your tasks:

  • Review of current fuel sloshing models
  • Review & analysis of ROM theory
  • Derivation / identification (incl. generation of Matlab tools) of ROM from test or simulation data, representing spacecraft sloshing / structure dynamics
  • Controller design and analysis for the derived ROM plants
  • Results and tools documentation

Requirements with respect to education and technical skills:

  • Enrolled  Master student (d/m/f) within Aerospace or Control Engineering, or similar field of study
  • Model reduction techniques
  • Flexible spacecraft dynamics and sloshing
  • Spacecraft modeling and simulation
  • Spacecraft attitude control
  • Matlab / Simulink
  • Programming skills in C/C++ and Matlab
  • Languages: English (German is an asset)
