A simplified Newton method to generate snapshots for POD models of semilinear optimal control problems
Paul Manns, Stefan Ulbrich
In PDE-constrained optimization, proper orthogonal decomposition (POD) provides a surrogate model of a (potentially expensive) PDE discretization, on which optimization iterations…
Identification of Model Uncertainty via Optimal Design of Experiments Applied to a Mechanical Press
Tristan Gally, Peter Groche, Florian Hoppe +5
In engineering applications almost all processes are described with the help of models. Especially forming machines heavily rely on mathematical models for control and condition mo…
Semi-automatically optimized calibration of internal combustion engines
Timo Burggraf, Michael Joswig, Marc E. Pfetsch +2
Modern combustion engines incorporate a number of actuators and sensors that can be used to control and optimize the performance and emissions. We describe a semi-automatic method…
Robust Shape Optimization of Electric Devices Based on Deterministic Optimization Methods and Finite Element Analysis With Affine Decomposition and Design Elements
Ion Gabriel Ion, Zeger Bontinck, Dimitrios Loukrezis +5
In this paper, gradient-based optimization methods are combined with finite-element modeling for improving electric devices. Geometric design parameters are considered by affine de…
