Control and Optimization with DAEs

Organizers: Vu Hoang Linh and Volker Mehrmann

Differential Algebraic Equations (DAEs) are mixed systems of differential and algebraic equations. It has been recognized for some time now that they have great potential both theoretically and in applications. DAEs form one of the most elegant and simple ways to model a physical system because they allow for the creation of separate models for subcomponents that can then be pasted together via a network. As a consequence, this concept is used in many modern CAD systems like SIMULINK, Scicos and DYMOLA although most software packages cannot fully exploit the full potential of DAE models.

But this nice feature of DAEs for modeling has also a disadvantage, since it shifts all of the difficulties of a system onto the analysis and the numerical methods. For this reason in recent years much effort is been spent to regularize general DAEs and to derive suitable numerical methods for optimization and control. It is therefore the goal of this minisymposium to inform about the state of the art in modeling, simulation, control and optimization of DAEs.
