Controllability and Positivity Constraints in Population Dynamics with age, size Structuring and Diffusion
Yacouba Simpore, Umberto Biccari
In this article, we consider the infinite dimensional linear control system describing the Population Models Structured by Age, Size, and Spatial Position. The control is localized…
Null Controllability for a Degenerate Structured Population Model
Yacouba Simporé, Yassine El gantouh, Umberto Biccari
In this paper, we consider the infinite dimensional linear control system describing population models structured by age, size, and spatial position. The diffusion coefficient is d…
Multilevel control by duality
Umberto Biccari, Enrique Zuazua
We discuss the multilevel control problem for linear dynamical systems, consisting in designing a piece-wise constant control function taking values in a finite-dimensional set. In…
Optimal control of linear non-local parabolic problems with an integral kernel
Umberto Biccari, Víctor Hernández-Santamaría, Loic Louison +1
We consider a linear non-local heat equation in a bounded domain , , with Dirichlet boundary conditions, where the non-locality is given by the prese…
Multilevel Selective Harmonic Modulation via Optimal Control
Umberto Biccari, Carlos Esteve-Yagüe, Deyviss Jesús Oroya-Villalta
We consider the Selective Harmonic Modulation (SHM) problem, consisting in the design of a staircase control signal with some prescribed frequency components. In this work, we prop…
Controllability properties from the exterior under positivity constraints for a 1-D fractional heat equation
Harbir Antil, Umberto Biccari, Rodrigo Ponce +2
We study the controllability to trajectories, under positivity constraints on the control or the state, of a one-dimensional heat equation involving the fractional Laplace operator…
