Research
My research interests are (in alphabetical order):
Distributed control and optimization, see, e.g.
- my subproject "Distributed control of smart grids" (grant 05M18SIA:2018/01 - 2020/12) within the BMBF project KONSENS (Konsistente Optimierung uNd Stabilisierung Elektrischer NetzwerkSysteme), see also https://konsens.github.io/
- participation in the project Distributed Optimization and Control of Networked Energy Systems (OptNetSys:2020/04 - 2022/03; Chinesisch-Deutsches Zentrum für Wissenschaftsförderung: Mobilitätsprogramm grant M-0007)
Mathematical systems theory, see, e.g.
- my subproject within the DFG project "System Theory of partial differential-algebraic equations" (grant WO 2056/1-1:2016/04 - 2020/10)
- my Heisenberg-professorship "Optimization-based Control" (DFG grant WO 2056/6-1:2019/07 - 2022/06)
- my subproject within the DFG project "Temperature controlled retinal laser treatment" (Temperaturgeregelte Laserbestrahlung der Netzhaut des Auges; grant WO 2056/7-1:2020/05 - 2022/04)
Model Predictive Control (MPC), see, e.g.
- my scientific network "Regulation of Mobile Robots using Model Predictive Control" funded by the DFG (grants WO 2056/2-1:2015/07 - 2016/12 and WO 2056/4-1:2017/09 - 2019/02)
