Abstract (Swedish)
In this thesis we discuss and test ways to improve the performance
of inline integration.
Inline integration is a tool used for real-time simulations of complex
dynamical systems. The idea is to relate information about the system
to the numerical method at a model level.
Real-time simulations of complex models have become standard in industry.
This puts high demands on simulation tools with regard to
computational speed.
Mixed mode integration is treating stiff variables and non-stiff variables
with different numerical methods, in doing so we expect to reduce the
dimensions of the non-linear systems that needs to be solved and hence
increase the computational speed. We investigate what mixed mode
integration means with inline... (More)
