In this paper, modeling of doubly fed induction generator (DFIG) based wind energy conversion system (WECS) and speed controller are presented. The System Identification Toolbox MatLab is used to develop the linear model WECS by considering as input output. Two models, namely Auto Regressive with eXogenous Input (ARX) Auto-Regressive Moving Average (ARMAX), estimated. We ARX221 structure best f...

New shape control implementations and dynamics studies on the National Spherical Torus eXperiment (NSTX) (Ono et al 2000 Nucl. Fusion 40 557–61) are summarized. In particular, strike point position, X-point height and squareness control, and two new system-identification methods/control-tuning algorithms were put into operation. The PID controller for the strike point was tuned by analysing the...

This paper addresses the problem of identifying echelon canonical forms for a vector autoregressive moving average model with exogenous variables using finite algorithms. For given values of the Kronecker indices a method for estimating the structural parameters of a model using ordinary least squares calculations is presented. These procedures give rise, rather naturally, to a technique for th...

Abstract This article tackles the challenge of negative pressure adhesion control a Vortex Robotic (VR) platform, which utilizes modified Electric Ducted Fan (EDF)-based design for successfully adhering to surfaces variable curvature. The resulting Actuation (VA) system is estimated through switching Autoregressive-Moving-Average with eXternal input (ARMAX) identification, accurately capturing ...

The study analyzed the impact of COVID-19 pandemic on carbon dioxide emissions from electricity generation. Additionally, monthly seasonality was taken into account. It assumed (research hypothesis) that both (expressed in individual waves infection cases) and month have a significant CO2 emissions. Analysis variance (ANOVA) non-parametric Kruskal–Wallis tests were used to evaluate significance...

The background of this research is to understand the operation process, which main goal developing process model. This model often used for operator training, design, safety system analysis, or control design. dynamic milk cooling from 36˚C 4˚C using chilled water available at 2˚C was performed. Chilled maintained a constant temperature by refrigerant unit. being investigated Packo brand tank b...
