Optimizing Control of Distributed Cyber-Physical Systems
(kassel university press, 2021)
In this thesis, a set of modeling and control strategies are proposed for Cyber-physical systems (CPS), which aim at ensuring a safe, reliable, and highly performant operation of each local subsystem contained in the CPS. Modeling of CPS is challenging since not only must the tight interconnection of continuous and discrete dynamics of local subsystems be exactly represented, but so must also the interleaving structure between different subsystems. Optimal control of CPS, accordingly, should take into account not ...

Optimization of multiphase permanent magnet synchronous machines on system level with reduced losses
(kassel university press, 2022)
Die Anforderungen an elektrische Maschinen in Elektrischen- und Hybrid- Elektrischen Fahrzeugen sind eine hohe Leistungsdichte, ein Stator und Rotor magnetisches Feld mit niedrigem Oberwelleninhalt und bestes akustisches Verhalten. Sechsphasige permanent magneterregte Synchronmaschinen zeigen signifikante Vorteile gegenüber den konventionellen dreiphasigen PMSMs, wie beispielsweise reduziertem Strom pro Phase im Umrichter, weniger Grundwellenverlusten aufgrund eines besseren Wicklungsfaktors und eine erhöhte ...

Grundlagen zur thermo-mechanisch induzierten Eigenschaftsgradierung von ausscheidungshärtbaren Aluminiumknetlegierungen
(kassel university press, 2023)
Inspired by industrial established steel forming strategies [Ste09d, Ste07a, Ste17], this study focuses on the effect of differential cooling on mechanical properties and precipitation kinetics during hot stamping of precipitation hardenable aluminum alloys, EN AW-6082 and EN AW-7075. For this aim, comprehensive process parameter studies are firstly carried out to investigate the resulting intrinsic material properties and microstructural evolution based on the complex mutual interactions of the thermo-mechanically ...
