Overview

Expertise

Experimental Modeling (Identification)

  • Building models from data, not from first principles (physical, chemical, ... laws)
  • Improving models from first principles with the help of measurement data (grey-box models)
  • Metamodeling: Fast models than approximate complex, time-consuming calculations. Suited for dynamic simulation, optimization, real-time application
  • Nonlinear and/or dynamic models

Design of Experiments

  • Where to measure?(not location but which operating points?)
  • How to describe the operating regime boundaries?

Input Selection

  • Which inputs are how relevant for modeling?
  • Which inputs have strongly nonlinear effects?

Classification, novelty detection, extrapolation detection, ...

Models: What For?

  • Models are the basis for most advanced techniques in many disciplines.
  • Model-based techniques can be divided into a (sometimes iterative) two-step procedure:
    1. Building a model.
    2. Using a technique based on this model.
  • Applications of models:
