Simulation-based design is a powerful tool assisting the development and maintenance of many engineering systems, for example in the high-tech, robotics or automotive domains. However, their increasing complexity in materials, components and physical requirements push classical model-based simulation techniques to their limits. Such systems are often modelled by
coupling separate subsystems of dynamical equations with highly heterogeneous properties. The reasons for such a modular approach are to support component-based design, different type of model hierarchies, or to allow for a multiphysical characterization of their dynamics. The repeated simulation, e.g., for optimization of such complex interconnected systems leads to prohibitively large simulation times, which makes an automated design process unfeasible.
One way to overcome this is by creating cheaper surrogate models, that are faster to evaluate. However, this come at the cost of accuracy. Recently, great advancements have been made in the field of data-based surrogate modelling, which uses machine learning methodologies to construct these reduced models. The aim of this project is to develop a framework to construct and analyse such (data-based) surrogate models of coupled dynamical systems with kinematic constraints.
Job Description Within this project you will work on developing a framework that enables the fast simulation of engineering systems that are (partially) modelled with a multibody systems approach. For that, you will use a data-based surrogate modelling approach and study appropriate simulation techniques for the resulting coupled, heterogeneous dynamical systems with constraints described with differential-algebraic equations. The main challenges and workpackages are:
- The appropriate handling of the constraints at subsystem level when generating the data-based surrogate models.
- The development of an analysis framework for the propagation of subsystem errors in the coupled system model, and of new methods to mitigate those errors.
- The development of methodologies to simulate the resulting heterogeneous system appropriately ensuring stability and reducing computation time.
EmbeddingYou will execute this project in the Autonomous and Complex Systems group of the Dynamics and Control (D&C) section at the Department of Mechanical Engineering of the Eindhoven University of Technology.
The mission of the Dynamics and Control Section, which consists of 22 faculty members and 45 researchers, is to perform research and train next-generation students on the topic of understanding and predicting the dynamics of complex engineering systems in order to develop advanced control, estimation, planning, and learning strategies which are at the core of the intelligent autonomous systems of the future: Designing and realizing smart autonomous systems for industry and society.
Moreover, the project will offer you an extensive training program in the scope of the Graduate School of Engineering Mechanics (
https://engineeringmechanics.nl/), and, within TU/e, focusing on more generic and transferable skills required by professional researchers. This provides you with a solid background for your research and future career.
