Boundary control systems on a one-dimension spatial domain - new paper co-authored by #ModConFlex researcher Bouchra Elghazi:
The paper studies when mathematical models of flexible structures with control at their boundaries are well posed. The authors identify the conditions under which the models can be fully controlled and observed.
This is useful for controlling and monitoring vibrations in structures like beams, aircraft wings, or wind-turbine blades.
#ModConFlex researcher Qian Liu recently co-authored a paper in #IEEE Transactions on Power Electronics journal.
It comprises research on developing advanced control strategies for inverter-based resources (e.g., solar photovoltaics, wind turbine generators) to ride through contingencies in electric grids.

The winner of this year's presentation prize is #ModConFlex researcher Albert Alcalde. Congratulations!!
In his presentation, Albert showed how #transformer models, the #NeuralNetworks used in language models, can be designed to perfectly learn relationships between sequences of data.
Albert's results help to explain why transformers are so effective at capturing complex patterns, providing new mathematical insight into their inner workings.

#ModConFlex third Network Meeting took place in the picturesque center of Besançon.
The management presentation and meetings were quickly followed by the 13 #MSCA researchers' presentations. While the presentations were overall above average, only one could win the presentation prize... .
The scientific teaching was provided not only by #HorizonEU project members but complemented by lectures from Denis Matignon (ISAE-SUPAERO) and Hector Ramirez (Universidad Tecnica Federico Santa Maria).
Usually, #ModConFlex researcher Vicente Ocqueteau works at the University of Bordeaux.
Currently, he is spending two months at the @uni_wuppertal , where he enjoys lively discussions with scientists working in the area of PDEs and functional analysis.
On Wednesday, he presented his research on floating objects to researchers from the Group of Functional Analysis, as well as some from the Collaborative Research Center “Port Hamiltonian Systems”.
This might be an interesting option also for #ModConFlex researchers after their PhD - #PostDoc fellowship:
A short report by #ModConFlex researcher Alan Valadez from ECCE 2025:
It was a pleasure to attend ECCE Europe 2025 in Birmingham and to present my work on “Enhancing Grid Stability with Synchronverter-Based Control for Grid-Side Converters in Wind Power Systems.”
My research focuses on applying a synchronverter-based control strategy for wind turbine grid-side converters.

We developed a new method to model the complex, flexible motion of aircraft wings using machine learning. This approach builds accurate, physics-informed models from simulation data, helping engineers design better wings and controls.

Tonight, #ModConFlex will be on TV!
A few weeks ago, a small team from regional TV passed by @uni_wuppertal to meet with our coordinator and one of the PhD students.
And tonight, our coordinator will also be interviewed live on TV. In a day or two, this should be available here:

➡️ method to simplify how flexible structures like aircraft wings vibrate when they bend and twist in complex, nonlinear ways. Automatically selects the most important vibration patterns to accurately represent this motion, simplifiying analysis and control.
Last week, several #ModConFlex researchers presented at the 5th IFAC Workshop on Control of Systems Governed by Partial Differential Equations - CDPE 2025 - at Beijing.
In total, 5 Ph.D. students from four different project nodes (Besançon, Tel Aviv, Twente and Wuppertal) and three supervisors attended.
Ignacio Diaz and Bouchra Elghazi were on the shortlist for the Young Author Award and Bouchra even won the prize in the end. Congratulations!
On Wednesday afternoon several of our #MSCA project's researchers present at the "Modelling and Control of Flexible Structures" session at the
5th IFAC Workshop on Control of Systems Governed by Partial Differential Equations (CPDE 2025)

Hybrid Schrödinger-Liouville and projective dynamics:
Arguably the most fundamental example of a hybrid system that alternates between continuous and discrete dynamics is a quantum system. We showed that its dynamics can be cast into one single equation on extended space which makes it amenable to port-theoretic description.

New paper by #ModConFlex researcher Zhuo Xu on the robustness of a fluid-particle interaction system.
"A distinctive feature, not yet considered in the ISS literature, is that our system involves a free boundary. More precisely, the fluid is described by the viscous Burgers equation, and the motion of the particle obeys Newton second law. ... The proof is based on the construction of a Lyapunov functional derived from a special test function."
#ModConFlex researcher Vicente Ocqueteau co-authored a study of small oscillations of a floating cylinder:
"On an Initial Value Problem Describing the Small Oscillations of a Floating Cylinder" (V.Ocqueteau and M.Tucsnak) establishes #existence, #uniqueness and #regularity results for the #solutions of the governing #equations.

Several PhD students and supervisors from the #ModConflex #EUhorizon #MSCA project met at the Spring School on Theory and Applications of Port-Hamiltonian Systems (PHS2025) last week.
The PhD students presented and discussed posters of their work. The supervisors presented, too, and the project coordinator was also involved in the organisation.
