A constraint-based optimization technique for estimating physical parameters of Jiles – Atherton hysteresis model

Brijesh Upadhaya, Paavo Rasilo, Lauri Perkkiö, Paul Handgruber, Anouar Belahcen, Antero Arkkio

Improperly fitted parameters for the Jiles–Atherton (JA) hysteresis model can lead to non-physical hysteresis loops when ferromagnetic materials are simulated. This can be…

An improved model for performances calculation in spoke-type permanent-magnet machines considering magnetization orientation and finite soft-magnetic material permeability

Ali Jabbari, Frédéric Dubas

In semi-analytical modeling of spoke-type permanent-magnet (PM) machines (STPMM), the saturation effect is usually neglected (i.e. iron parts are considered to be infinitely…

Jafar Tavoosi

The purpose of this paper is to present a novel intelligent backstepping sliding mode control for an experimental permanent magnet synchronous motor.

Use of current sheet coupled to an analytical tool to analyze by FEM the harmonic content of armature winding ditribution

Jérôme Marault, Abdelmounaïm Tounzi, Frédéric Gillon, Michel Hecquet

For a given rotor, the study of the impact of stator MMF from different winding distributions is usually carried out using analytical model under some simplifying hypotheses to…

Modelling and dynamic state estimation of a doubly fed induction generator wind turbine

Sayyed Ali Akbar Shahriari

This paper aims to propose an 18th-order nonlinear model for doubly fed induction generator (DFIG) wind turbines. Based on the proposed model, which is more complete than the…

Moore-Penrose pseudo-inverse and artificial neural network modeling in performance prediction of switched reluctance machine

Ana Camila Ferreira Mamede, José Roberto Camacho, Rui Esteves Araújo, Igor Santos Peretta

The purpose of this paper is to present the Moore-Penrose pseudoinverse (PI) modeling and compare with artificial neural network (ANN) modeling for switched reluctance machine…
