Data-driven Discovery of Delay Differential Equations with Discrete Delays
Alessandro Pecile, Nicola Demo, Marco Tezzele +2
The Sparse Identification of Nonlinear Dynamics (SINDy) framework is a robust method for identifying governing equations, successfully applied to ordinary, partial, and stochastic…
Viability and control of a delayed SIR epidemic with an ICU state constraint
Dimitri Breda, Matteo Della Rossa, Lorenzo Freddi
This paper studies viability and control synthesis for a delayed SIR epidemic. The model integrates a constant delay representing an incubation/latency time. The control inputs mod…
Sparse identification of time delay systems via pseudospectral collocation
Enrico Bozzo, Dimitri Breda, Muhammad Tanveer
We present a pragmatic approach to the sparse identification of nonlinear dynamics for systems with discrete delays. It relies on approximating the underlying delay model with a sy…
Lyapunov exponents of renewal equations: numerical approximation and convergence analysis
Dimitri Breda, Davide Liessi
We propose a numerical method for computing the Lyapunov exponents of renewal equations (delay equations of Volterra type), consisting first in applying a discrete QR technique to…
