- Title: Multiobjective Optimization of Non-Smooth PDE-Constrained Problems - Switches, State Constraints and Model Order Reduction
Description: Joint project with the University of Konstanz (Prof. Dr. Stefan Volkwein), where we address multiobjective optimization and optimal control problems with non-smooth PDE constraints. In order to increase the numerical efficiency, model order reduction techniques such as Proper Orthogonal Decomposition (POD) are used, and we develop error bounds to obtain convergent algorithms.
Project Funding:DFG Priority Programme 1962 "Non-Smooth and Complementarity-Based Distributed Parameter Systems: Simulation and Hierarchical Optimization"
- Title: Simultaneous Development and Testing of Cyber Physical Systems (CPS) using the example of autonomous electric vehicles (SET CPS)
Description: Joint project with dSPACE and e.GO, where we join the development and testing process of autonomous electric vehicles using multiobjective optimization in order to significantly accelerate the development of new cars (Further information (in german))
