I have added the slides of my talk “Instability in Power Systems due to Switching” given at the GAMM-FA meeting in Kassel on my Talks page.
Paper on indiscernible topological changes submitted
We have submitted the manuscript
Indiscernible topological variations in DAE networks Journal Article In: Automatica, vol. 101, pp. 280-289, 2019. |
for publication. It is an extension of our IFAC paper
Indiscernible topological variations in DAE networks with applications to power grids Proceedings Article In: Proc. 20th IFAC World Congress 2017, pp. 7333 - 7338, Toulouse, France, 2017, ISSN: 2405-8963. |
where we extended the results to the MIMO case and also fully characterize the set of indiscernible initial states. Furthermore, we present sufficient conditions for regularity preserving topological changes.
Preprint on observer design for detectable switched DAEs available
We have submitted our manuscript
Detectability and observer design for switched differential algebraic equations Journal Article In: Automatica, vol. 99, pp. 289-300, 2019. |
for publication. We hope to receive constructive reviews soon.
First day in new office
Today was my first day at the University of Groningen. I was able to set up my new email-address and I also have a phone in my office (room 390 in Bernoulliborg), see my new contact-website.

Kaiserslautern → Groningen
I am currently in the process of moving from the University of Kaiserslautern (Germany) to the University of Groningen (Netherlands) from which I have received an offer for a permanent position as Associate Professor for Systems and Control within the Johann Bernoulli Institute for Mathematics and Computer Science. I will start in Groningen in November and as soon as I have a website with my new contact details, I will update my About Me page. My uni-kl-email-address will be valid until March 2018, so you can still reach me with the old email-address for a while.
The first five years in Groningen will actually be paid by my Vidi-grant which I obtained for my project proposal entitled “Analysis and Control of Switched Differential Algebraic Equations”. In the near future I will add a project page with more details about this project. To get a first idea, see the public summary in the list of Vidi Awards 2016, the corresponding press release of the University of Groningen, or the press release of the Faculty of Science and Engineering.
IFAC Interactive Paper Prize Finalist
Our IFAC paper
Switch observability for homogeneous switched DAEs Proceedings Article In: Proc. 20th IFAC World Congress 2017, pp. 9355 - 9360, Toulouse, France, 2017, ISSN: 2405-8963. |
was finalist for the IFAC Congress Interactive Paper Prize! After the original certificate had some typos we now have received a corrected version:
Welcome
My name is Stephan Trenn and I am researcher in the area of applied mathematics, for more informations see the About Me page. You may also want to browse my publications, which can be filtered e.g. by keywords and coauthors. I also have profiles at Google Scholar, ResearchGate and ORCID.
Below, I will regularly post news related to my research.
Finally, my Erdös number (see also here) is 4.

List of talks (with slides) online
I have copied the list of talks (including all slides) from my old website to the Talks page.
CDC 2017 final preprints online
For the CDC 2017 in Melbourne my coauthors and I have submitted four papers which were all accepted for publication. We have now prepared the final versions and I have uploaded the preprints:
