Automated Model Updating of Digital Twins

The project aims at developing methods and tools for improving model accuracy by enrichment and real-time updating of dynamical systems and multi-physics models, using data from downstream or upstream processes of the entire value chain. Thus, it will enable the creation of data-enriched digital twins that are accurate digital representations of the physical process, such that these can be used for:

  • design,
  • optimization, and
  • decision-making.

Consequently, these hybrid models come with a variety of objectives and innovations:

  • multiple heterogeneous physics-based models can be compared w.r.t. relevancy and accuracy,
  • data can be heterogeneous and asynchronous and come from sources located anywhere in the system, i.e., from upstream processes, as well as from downstream processes.

Challenges

The scientific challenges of this project are:

  • How do we perform real-time updating of dynamical systems and multi-physics models using big-data from the entire value chain?
  • How to develop methods for the automated and real-time updating and enrichment of dynamic models based on data, while taking uncertainty and model complexity into account?
  • How to develop statistical methods for the automated selection of hybrid models that appropriately trade- off complexity with accuracy, resulting in optimal generalizability?

The goal is to obtain adaptive digital twins with limited complexity that guarantee up-to-the-minute accurate digital representation of the physical systems. As a result, they will become the building blocks for the digital twins used in Projects 4 and 5.

2.1 Autonomous updating of dynamic models for redesign of engineering systems

Ir. Bas M. Kessels

In the Dynamics and Control group, part of the Mechanical Engineering faculty of the Eindhoven University of Technology, Bas works as a PhD candidate in the Digital Twin project. He focuses on methods with which mechanical models can be updated using sensor data, such that agreement between physical structures and their models is achieved throughout their lifetimes.
