The Regional Boundary Reconstruction Problem of the Initial State for Fractional Semilinear Systems

Khalid Zguaid, Fatima Zahrae El Alaoui, Delfim F. M. Torres

Observability is a fundamental concept in control theory. Its primary purpose is to look into whether it is possible to reconstruct the system's initial state using only the inform…

Safe and wind-aware synchronous path planning for a fleet of fixed-wing constant speed aircraft

Maël Feurgard, Gautier Hattenberger, Nicolas Durand +1

Path planning for multiple unmanned aerial vehicles is a difficult task, and even more for a fleet of fixed-wing aircraft. One specific case is the transition to, or between, forma…

A Koopman Operator Framework for Nonlinear Epidemic Dynamics: Application to an SIRSD Model

Achraf Zinihi, Matthias Ehrhardt, Moulay Rchid Sidi Ammi

We develop and analyze an SIRSD epidemic model, which extends the classical SIR framework by incorporating waning immunity and disease-induced mortality. A rigorous well-posedness…
