The theory of enabling control explains how the development and design of performance measurement systems (PMSs) induce subordinate managers to experience PMSs as enabling. However, PMSs are often vital to superior managers' control. The empirical re

We consider dynamic optimization problems for systems described by differential-algebraic equations (DAEs). Such problems are usually solved by discretizing the full DAE. We propose techniques to symbolically eliminate many of the algebraic variables

During the last three decades, a vast variety of methods to numerically solve ordinary differential equations and differential-algebraic equations has been developed and investigated. The methods are mostly freely available in different programming l

This paper presents a decomposition strategy applicable to DAE constrained optimization problems. A common solution method for such problems is to apply a direct transcription method and solve the resulting nonlinear program using an interior-point a

A dynamic model of a chemical CO2 absorption process with aqueous monoethanolamine (MEA) is presented, validated against experimental data. Based on the validated model, a reduced-order model is developed, suitable for an online optimization control

The equation-based Modelica language allows the modeller to specify custom functions. The body of a function is an algorithm that contains procedural code to be executed when the function is called. This language feature is useful for many applicatio

Constructing compilers using ordinary object-oriented programming takes advantage of parser generators to construct abstract syntax trees (ASTs) and uses the Visitor design pattern to program traversals that resolve names and types and to generate co

This paper presents results from time-optimal path tracking for industrial robots. More specifically, three subproblems are studied and experimentally evaluated. The first is a contact-force control approach for determining the geometric robot motion
