AA Zazerani, A Faraji… - IET Control Theory & …, 2022 - Wiley Online Library
Generally multi‐model controllers design has three stages: Decomposition of complicated
non‐linear systems into local linear models, designing the local controllers, and composition …

On the exact controllability of a Galerkin scheme for 3D viscoelastic fluids with fractional Laplacian viscosity and anisotropic filtering

L Bisconti, D Catania - ZAMM‐Journal of Applied Mathematics …, 2024 - Wiley Online Library
We study a mathematical model describing 3D viscoelastic fluids with memory, fractional
viscosity, and regularized by means of a horizontal anisotropic filter. This regularization is …

Lack of complete stabilizability of some coupled ode-parabolic systems

D Maity, D Mitra, M Ramaswamy - 2021 - hal.science
In this article, we consider several coupled ode-parabolic systems. These systems are
known to be not null controllable at any time by localized interior controls. We show that …
