Smart Structures Innovations Using Robust Control Methods

Applied Mechanics, 2023
This study’s goal is to utilize robust control theory to effectively mitigate structural oscillations in smart structures. While modeling the structures, two-dimensional finite elements are used to account for system uncertainty. Advanced control methods

Algorithm for parametric synthesis of cascade-connected matching mixed quadripoles according to the criterion of ensuring stationary generation mode

Физика волновых процессов и радиотехнические системы, 2022
Introduction: the analysis of the well-known literature shows that the use of various types of four-pole devices (reactive, resistive, complex) allows to increase the area of physical feasibility of the stationary generation mode. The purpose of the work:

Bi-layer optimal secondary frequency control approach for energy storage clusters considering wind power uncertainty

Frontiers in Energy Research, 2022
Increasing penetration of wind power with intermittency and variability threatens the stability of the power system frequency. The fast response capability of the energy storage system (ESS) makes it an effective measure to improve frequency regulation ...

Quantum robust control theory for Hamiltonian and control field uncertainty

New Journal of Physics, 2021
Quantum robust control—which can employ fast leading order approximations, slower but more accurate asymptotic methods, or a combination thereof for quantification of robustness—enables control of moments of quantum observables and gates in the presence ...

An Approximation Method for Fractional-Order Models Using Quadratic Systems and Equilibrium Optimizer

Fractal and Fractional, 2023
System identification is an important methodology used in control theory and constitutes the first step of control design. It is known that many real systems can be better characterized by fractional-order models.

Identification of linear response functions from arbitrary perturbation experiments in the presence of noise – Part 1: Method development and toy model demonstration [PDF]

Nonlinear Processes in Geophysics, 2021
Existent methods to identify linear response functions from data require tailored perturbation experiments, e.g., impulse or step experiments, and if the system is noisy, these experiments need to be repeated several times to obtain good statistics.

Virtual oscillator‐based methods for grid‐forming inverter control: A review

IET Renewable Power Generation, 2022
In inverter‐dominant power systems, grid‐forming (GFM) inverters regulate voltage and frequency. To construct GFM inverters, conventionally, various control methods based on synchronous machine emulation or droop characteristics have been employed ...
