Master Thesis “Analysis of the limitations by estimated sensitivities in the co-simulation”

Virtual Vehicle Research GmbH, Graz

VIRTUAL VEHICLE is a leading international R&D center for the automotive and rail industries. The center focuses on advanced virtualization of vehicle development. This linking of numerical simulations and hardware testing leads to a powerful HW-SW system design.

In the co-simulation of dynamic systems, the focus is on the comprehensive and networked simulation of domain-specific subsystems. The different dynamics of the subsystems typically lead to stiff overall systems and limit the performance of classical solution approaches. A way out is the use of input / output sensitivities of the subsystems, which, however, are usually not available and therefore have to be identified. In this work methods for determining the sensitivities and the influence of the estimation on the cosimulation are to be investigated. Based on examples, the limitations should be presented.
