In this paper, an efficient method is proposed for detecting and locating a soft fault, i.e. a physical degradation, in a Y-shaped network of unshielded twisted pair cables. The method uses jointly the observability analysis and time-frequency domain reflectometry experimental measurements. The fault detection consists in checking the consistency b...

In this paper, a full nonlinear control of a variable-pitch wind system (VPWS) based on the doubly fed induction generator (DFIG) fed by a direct matrix converter (DMC) has been presented. In this context, The MPPT has been implemented using the third order sliding mode control (TOSMC) in order to ensure maximum power provided by the wind turbine o...

This paper introduces a novel methodology for business process simulation, focusing on the incremental transformation of Business Process Modeling and Notation (BPMN) models enriched with Business Process Simulation Interchange Standard (BPSIM) elements into the Discrete Event System Specification (DEVS) formalism. The proposed method enhances the ...

The Industrial Internet of Things (IIoT) presents numerous requirements, such as reliability, energy efficiency, and real-time performance, among others. Digital Twins technology addresses these needs by enabling the simulation, monitoring, and optimization of such systems. Specifically, Network Digital Twins (NDTs) have recently attracted signific...

In this paper, we analyze the stability of quasilinear systems on time scale based on a new estimation of the upper bound of the time scale matrix exponential function. First, some upper bounds for the norm of the matrixexponential function eA(t, t0) are derived, where A is a regressive square matrix, t, t0 ∈ T, T being an arbitrary nonempty closed...

Recently, the concept of k-contraction has been introduced as a promising generalization of contraction for dynamical systems. However, the study of k-contraction properties has faced significant challenges due to the reliance on complex mathematical objects called matrix compounds. As a result, related control design methodologies have yet to appe...

Bien qu'ils soient de plus en plus performants, les systèmes cyberphysiques demeurent sensibles aux cyberattaques. Cet article porte sur les appareils de voie de l'infrastructure de transport ferroviaire. Pour de tels systèmes, les données surveillées sont géographiquement dispersées, ce qui les rend particulièrement vulnérables : les attaquants pe...

This thesis focuses on designing robust output-feedback backstepping-based controllers for hyperbolic partial differential equation (PDE) systems interconnected in a chain structure. We take advantage of connections between the class of hyperbolic PDE systems under consideration and time-delay systems of the neutral type presented in Part I. Then, ...
