Stability Criterion of Subsynchronous Oscillation of Direct Drive Permanent Magnet Synchronous Generator Based on Impedance Polynomial Fitting

open access: yes发电技术, 2020
Impedance analysis is the leading method of solving the stability issues of grid-connected renewable energy generation systems. Taking the grid-connected system of direct drive permanent magnet synchronous generator (D-PMSG) as an example, the ...

FEEDBACK STABILIZATION OF HOMOGENEOUS POLYNOMIAL SYSTEMS [PDF]

open access: yesIFAC Proceedings Volumes, 1995
The propose of this paper is to drive a simple necessary and sufficient stabilizability condition for a class of multi-inputs polnomial systems. This result represents a generalization of the main theorems of (Iggidr and Vivalda, 1992). The stabilizing feedbacks are explicitly given.

The Stability Interval of the Set of Linear System [PDF]

open access: yesInternational Journal of Electronics and Telecommunications, 2021
The article considers the problem of stability of interval-defined linear systems based on the Hurwitz and Lienard- Shipar interval criteria. Krylov, Leverier, and Leverier- Danilevsky algorithms are implemented for automated construction and analysis of

Decaimiento Polinomial y Modelaje Numérico Computacional de la viga de Timoshenko con disipación parcial

open access: yesSelecciones Matemáticas, 2018
We studied the uniform stabilization of a class of Timoshenko systems with partial dissipation of the beam. Our main result is to prove that the semigroup associated to this model has polynomial decay.

Stability and Fourier-Mukai Transforms on Higher Dimensional Elliptic Fibrations [PDF]

open access: yes, 2015
We consider elliptic fibrations with arbitrary base dimensions, and generalise previous work by the second author. In particular, we check universal closedness for the moduli of semistable objects with respect to a polynomial stability that reduces to PT-

Les polynômes eul\IeC èriens stables de type B [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2012
We give a multivariate analog of the type B Eulerian polynomial introduced by Brenti. We prove that this multivariate polynomial is stable generalizing Brenti's result that every root of the type B Eulerian polynomial is real.

Analysis and Design of Robust Controller for Polynomial Fractional Differential Systems Using Sum of Squares

open access: yesAxioms, 2022
This paper discusses the robust stability and stabilization of polynomial fractional differential (PFD) systems with a Caputo derivative using the sum of squares. In addition, it presents a novel method of stability and stabilization for PFD systems.

Conic stability of polynomials [PDF]

open access: yesResearch in the Mathematical Sciences, 2018
We introduce and study the notion of conic stability of multivariate complex polynomials in $\mathbb{C}[z_1,\ldots, z_n]$, which naturally generalizes the stability of multivariate polynomials. In particular, we generalize Borcea's and Br nd n's multivariate version of the Hermite-Kakeya-Obreschkoff Theorem to the conic stability and provide a ...

Probabilistic small-signal stability analysis of power systems based on Hermite polynomial approximation

open access: yesSN Applied Sciences, 2021
This paper proposes a probabilistic small-signal stability analysis method based on the polynomial approximation approach. Since the correct determination of unknown coefficients has a direct effect on the accuracy of the polynomial approximation method,

Gridding discretization-based multiple stability switching delay search algorithm: The movement of a human being on a controlled swaying bow. [PDF]

open access: yesPLoS ONE, 2017
Delay represents a significant phenomenon in the dynamics of many human-related systems-including biological ones. It has i.a. a decisive impact on system stability, and the study of this influence is often mathematically demanding. This paper presents a
