Realization in Generalized State Space form for 2-D Polynomial System Matrices

Sultan Qaboos University Journal for Science, 2005
In this paper, a direct realization procedure is presented that brings a general 2-D polynomial system matrix to generalized state space (GSS) form, such that all the relevant properties including the zero structure of the system matrix are retained.

System Identification Based ARV-MPPT Technique for PV Systems Under Variable Atmospheric Conditions

IEEE Access, 2022
Different tracking algorithms have been developed to obtain maximum efficiency from the PV power systems under changing atmospheric conditions. Some of these algorithms are effective under uniform irradiance, while the others are effective under partial ...

FEEDBACK STABILIZATION OF HOMOGENEOUS POLYNOMIAL SYSTEMS [PDF]

IFAC 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.

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

Advanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Decentralized Fuzzy Polynomial Observer Synthesis for Large-Scale Nonlinear System With Arbitrary Faults and Uncertainties

IEEE Access
This paper proposes a method to synthesize a decentralized polynomial observer for the large-scale nonlinear system. The polynomial Takagi-Sugeno (T-S) fuzzy framework is employed to model the large-scale nonlinear system to increase the accuracy and ...

Decomposing Polynomial Systems into Simple Systems

Journal of Symbolic Computation, 1998
A polynomial system \([P,Q]\) is a pair of multivariate polynomial sets \(P\) and \(Q\) and Zero \(([P,Q])\) is the set of all common zeros of the polynomials in \(P\) which are not zeros of any polynomial in \(Q\). Fixing an ordering to the variables, a simple system is a polynomial system ordered in triangular form, in which every polynomial is ...

Investigation of Laser Ablation and Brush Pre‐Treatments for AlCu Cold Roll Bonding in Oxygen‐Free Conditions

Advanced Engineering Materials, EarlyView.
It is shown that laser ablation pretreatment under oxygen‐free conditions enables copper–aluminium bonding at significantly lower deformation degrees and improved properties compared to mechanical brushing. Laser ablation further increases interface contact area and induces favourable residual stress states and microstructural compatibility ...

Tuning the controller for object models with one to four poles using the polinomial method

Journal of Engineering Science (Chişinău)
The paper describes the procedure for tuning the controller for control object models with one to four poles using the polynomial method, by imposing the damping ratio and the settling time of the synthesized system.

Polynomial $f(R)$ Palatini cosmology -- dynamical system approach

, 2017
We investigate cosmological dynamics based on $f(R)$ gravity in the Palatini formulation. In this study we use the dynamical system methods. We show that the evolution of the Friedmann equation reduces to the form of the piece-wise smooth dynamical ...
