This paper studies the solution accuracy of direct single-shooting in comparison to the
solution of the continuous optimal control problem (OCP). First, a convergence relation …

Simulation software has become an indispensable instrument for research and development
in the academic as well as the industrial environment. In many cases computer simulations …

An adjoint sensitivity method is presented for nonsmooth semiexplicit differential-algebraic
equation systems (NDAEs) of index 1. The adjoint sensitivity system is derived for a …

The adaptive switching structure approach is generalized from single-stage problems and
single-shooting to multi-stage problems and multiple-shooting. This generalization is based …

Adjoint code development for many-core architectures like GPUs is a major challenge. To
address issues arising from the parallelization, currently hand-writing the adjoint code is the …

Mankind wanted to use the possibility of the rotation long-long time ago, using the technical
advancement of the age. An example of this is the wheel, the horse-mill of the antiquity and …

A technique for optimizing large-scale differential-algebraic process models under
uncertainty using a parallel embedded model approach is developed in this article. A …

Considering the increasing number of modern thermodynamic models for engineering
applications and their continuously growing algebraic complexity, in the chemical process …

This work is based on the PhD thesis [1]. In contrast to multi-step methods [2], one
stepmethods applied to semi-explicit DAE systems of index 1, result in differential discrete …
