Process Technology

The process engineering group is involved in industrial continuous transport and conditioning processes, high volume air conditioning, closed loop steam processes for mobile applications and river reach and canal management. In all of these fields of application, distributed parameter systems and methods are used for modelling, simulation, feedforward and feedback control design.

Student's Theses

We are always looking for students, who want to contribute to one of our research projects through a bachelor's or master's thesis. The assigned subjects typically include but are not limited to:

  • Distributed-parameter modeling of mechanical, electric and thermodynamic systems.
  • Solving inverse mathematical problems.
  • Methods of constrained and unconstrained optimization.

If you are interested in one of our projects and would like to get more information, or if you'd like to inquire about additional topics, please don't hesitate to contact us.
