Journal ArticleDOI
A control oriented guided tour in oilwell drilling vibration modeling
Belem Saldivar,Sabine Mondié,Silviu-Iulian Niculescu,Hugues Mounier,Islam Boussaada,Islam Boussaada +5 more
TL;DR: An overview of the modeling of axial and torsional self-excited drilling vibrations is presented, allowing a proper system characterization and the identification of the vibration sources to avoid them or mitigate their influence.
Journal ArticleDOI
Further remarks on the effect of multiple spectral values on the dynamics of time-delay systems. Application to the control of a mechanical system
TL;DR: In this paper, a new interesting property of linear time-delay systems was emphasized and a multiplicity induced stability criteria for reduced order systems; scalar delay-equations and a special class of second order systems.
Journal ArticleDOI
Tracking the Algebraic Multiplicity of Crossing Imaginary Roots for Generic Quasipolynomials: A Vandermonde-Based Approach
TL;DR: The constructive approach in investigating the multiplicity of crossing imaginary roots jω where ω ≠ 0 and establishes a link with a new class of functional confluent Vandermonde matrices is extended and a bound sharper than the Polya-Szegö generic bound arising from the principle argument is established.
Journal ArticleDOI
Characterizing the Codimension of Zero Singularities for Time-Delay Systems
TL;DR: In this paper, the authors consider the case when the zero spectral value is multiple and show that the dimension of the projected state on the center manifold is none other than the sum of the dimensions of the generalized eigenspaces associated with spectral values with zero real parts.
Journal ArticleDOI
Multiplicity-induced-dominancy in parametric second-order delay differential equations: Analysis and application in control design
TL;DR: In this article, a parametric multiplicity-induced dominancy property is characterized, allowing to a delayed stabilizing design with reduced complexity, where the candidates' delays and gains result from the manifold defining the maximal multiplicity of a real spectral value, then, the dominancy is shown using the argument principle.
