Hammerstein-Wiener systems present a structure consisting of three serial cascade blocks. Two are static nonlinearities, which can be described with nonlinear functions. The third block represents linear dynamic component placed between the first two Some common model structures include rational-type transfer function, orthogonal rational functions (ORF), finite impulse response (FIR), autoregr...

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...

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...
