Dissipative estimator (observer) design for continuous time-delay systems poses a significant challenge when multiple pointwise and general distributed delays (DDs) are …
As widely known, the basic reproduction number plays a key role in weighing birth/infection and death/recovery processes in several models of population dynamics. In this general …
We apply the pseudospectral discretization approach to nonlinear delay models described by delay differential equations, renewal equations, or systems of coupled renewal equations …
This work presents a theoretical framework for the safety‐critical control of time delay systems. The theory of control barrier functions, that provides formal safety guarantees for …
Regenerative chatter vibrations arising during machining operations are a severe problem affecting the manufacturing production of high-precision mechanical components. A …
We contribute a full analysis of theoretical and numerical aspects of the collocation approach recently proposed by some of the authors to compute the basic reproduction …
XA Ji, G Orosz - Nonlinear Dynamics, 2024 - Springer
This paper focuses on learning the dynamics of time delay systems from trajectory data and proposes the use of the maximal Lyapunov exponent (MLE) as an indicator to describe the …
Q Feng, SK Nguang - Systems & Control Letters, 2016 - Elsevier
This paper examines the problem of stabilizing linear distributed delay systems with nonlinear distributed delay kernels and dissipativity constraints. Specifically, the nonlinear …
