Model order reduction via Lie groups
Yannik P. Wotte, Patrick Buchfink, Silke Glas +2
Lie groups and their actions are ubiquitous in the description of physical systems, and we explore implications in the setting of model order reduction (MOR). We present a novel fr…

Symmetric Lyapunov Subcenter Manifolds for Periodic Regulation of Mechanical Systems
Yannik P. Wotte, Arne Sachtler, Alin Albu-Schäffer +2
Multi-body mechanical systems have rich internal dynamics, whose solutions can be exploited as energy-efficient control targets. Yet, solutions non-trivially depend on system param…
