Distributed Economic Dispatch Control via Saddle Point Dynamics and Consensus Algorithms

IEEE Transactions on Control Systems Technology, 2019
In this brief, a distributed control algorithm is proposed to solve the economic dispatch problem. Without a central control unit, the generators work collaboratively to minimize the generation cost while balancing the supply and demand.

A Q‐Learning Algorithm to Solve the Two‐Player Zero‐Sum Game Problem for Nonlinear Systems

International Journal of Adaptive Control and Signal Processing, Volume 39, Issue 3, Page 566-581, March 2025.
A Q‐learning algorithm to solve the two‐player zero‐sum game problem for nonlinear systems. ABSTRACT This paper deals with the two‐player zero‐sum game problem, which is a bounded L2$$ {L}_2 $$‐gain robust control problem. Finding an analytical solution to the complex Hamilton‐Jacobi‐Issacs (HJI) equation is a challenging task.

Kuramoto Phase Model with Inertia: Bifurcations Leading to the Loss of Synchrony and to the Emergence of Chaos

Моделирование и анализ информационных систем, 2015
We consider a finite-dimensional model of phase oscillators with inertia in the case of star configuration of coupling. The system of equations is reduced to a nonlinearly coupled system of pendulum equations.

Enhanced Electromechanical Response in 1D Hybrid Perovskites: Coexistence of Normal and Relaxor Ferroelectric Phases

Advanced Functional Materials, EarlyView.
The dynamic polarization reversal of coexisting normal and relaxor ferroelectrics in 1D TMAPbI₃ (tetramethylammonium, TMA) is deciphered through combined experimental and theoretical approaches. By bridging atomic‐scale motion, macroscopic polarization switching, and depolarization effects, a universal methodology is established to engineer next ...

Practical debiasing with the Covariant Prior in the proportional regime when p < n

Journal of Physics Communications
We show that the Covariant Prior can be used to effectively de-bias the resulting MAP estimator in the proportional regime, where the number of covariates p grows proportionally to n , the number of samples, with p

Microplate Active Migration Emerging From Light‐Induced Phase Transitions in a Nematic Liquid Crystal

Advanced Functional Materials, EarlyView.
A quasi‐2D, light‐absorbing platelet embedded in a thermotropic nematic liquid crystal is activated with light irradiation. Depending on the light intensity, the platelet induces a localized nematic‐isotropic phase transition that triggers the motion. Using different confinements, the platelet can glide in a 2D regime or tilt and glide in a 3D regime ...

Structurally unstable quadratic vector fields of codimension two: families possessing a finite saddle-node and an infinite saddle-node

Electronic Journal of Qualitative Theory of Differential Equations, 2021
In 1998, Artés, Kooij and Llibre proved that there exist 44 structurally stable topologically distinct phase portraits modulo limit cycles, and in 2018 Artés, Llibre and Rezende showed the existence of at least 204 (at most 211) structurally unstable ...

The Antitriangular Factorization of Saddle Point Matrices [PDF]

SIAM Journal on Matrix Analysis and Applications, 2014
Mastronardi and Van Dooren [SIAM J. Matrix Anal. Appl., 34 (2013), pp. 173--196] recently introduced the block antitriangular (``Batman'') decomposition for symmetric indefinite matrices. Here we show the simplification of this factorization for saddle point matrices and demonstrate how it represents the common nullspace method.

Computational Modeling of Reticular Materials: The Past, the Present, and the Future

Advanced Materials, EarlyView.
Reticular materials are advanced materials with applications in emerging technologies. A thorough understanding of material properties at operating conditions is critical to accelerate the deployment at an industrial scale. Herein, the status of computational modeling of reticular materials is reviewed, supplemented with topical examples highlighting ...
