In the future of Smart Grids, many different devices have to be integrated into one overall system. These devices are of various types, they are related to various forms of energy, they have to exchange these different forms of energy, and together they have to work towards common objectives. To handle such a system, a general model is required, which allows the integration of all these differe...

This paper addresses the water temperature control in condensing domestic boilers. The main challenge of this process under the controller design perspective is the fact that the dynamics of condensing boilers are strongly affected by the demanded water flow rate. Two approaches are presented in this paper. First, a robust PI controller is designed that stabilizes and achieves good performance ...

We consider the dynamic shortest path problem in the continuous-time model because of its importance. This problem has been extensively studied in the literature. But so far, all contributions to this problem are based on the assumption that all transit times are strictly positive. However, in order to study dynamic network flows it is essential to support negative transit times since they occu...
