Translated title of the contribution: Modelling and control of conditioning units for test beds

Research output: ThesisDoctoral Thesis


How can air and other gases (media) be manipulated so that they behave in a desired way (conditioning)? To that end, the behaviour of air has to be understood (modelling)—this knowledge can then be exploited (control). In principle, these two sentences summarise the thesis at hand; however, the focus is on automotive test bed applications. At first, fundamentals of thermodynamics and fluid mechanics are revised (from a control engineer’s point of view). Then, pressure control is discussed in detail for an ideal gas inside a pipe, with a focus on the modelling of orifices (valves, flaps) and pipes; in particular, resonance phenomena are dealt with and the models are experimentally validated. Attention was paid to the practical use of the control schemes given, including the treatment of resonance phenomena. At last, temperature and humidity are considered—mainly in terms of modelling—, primarily including the modelling of steam boilers (which are a prerequisite to humidity control). Detailed and comprehensible derivations—with annotations from a controlengineer’s perspective—characterise the thesis at hand, which possibly facilitates the approaching of the treated subjects (especially the modelling) and shows starting points for potential adaptations.
