Optimal current waveforms for switched-reluctance motors [PDF]
2016 IEEE Conference on Control Applications (CCA), 2016 In this paper, we address the problem of finding current waveforms for a switched reluctance motor that minimize a user-defined combination of torque ripple and RMS current. The motor model we use is fairly general, and includes magnetic saturation, voltage and current limits, and highly coupled magnetics (and therefore, unconventional geometries and ...

Journal of the Association for Information Science and Technology, EarlyView.Abstract The emergence of generative artificial intelligence (GenAI) is reshaping the research landscape and carries significant implications for Digital Humanities (DH), a field long intertwined with computational methods and technologies. This study examines how DH scholars are adopting and critically evaluating GenAI in their research. Drawing on an

A priori error estimation of magnetic material characteristics using stochastic uncertainty analysis [PDF]
, 2010 By interpreting electromagnetic or mechanical measurements with a numerical model of the considered electromagnetic device, magnetic properties of the magnetic circuit of that device can be estimated by solving an inverse numerical electromagnetic ...

Flux-linkage characteristics of switched reluctance motor [PDF]
Proceedings of International Conference on Power Electronics, Drives and Energy Systems for Industrial Growth, 2002 An important requirement in the modelling of switched reluctance motors (SRM) is the knowledge of their flux-linkage characteristics. Idealisation of the flux-linkage characteristics will result in a model which cannot predict the performance of the machine with sufficient accuracy. It is necessary therefore to determine flux-linkage characteristics as

Early evolutionary history of the seed
Biological Reviews, EarlyView.ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Adaptive neuro-fuzzy controller of switched reluctance motor [PDF]
Serbian Journal of Electrical Engineering, 2007 This paper presents an application of adaptive neuro-fuzzy (ANFIS) control for switched reluctance motor (SRM) speed. The ANFIS has the advantages of expert knowledge of the fuzzy inference system and the learning capability of neural networks.

SYSTEMATIC DESIGN PROCEDURE OF SWITCHED RELUCTANCE MOTORS [PDF]
The International Conference on Electrical Engineering, 1999 While numerical analysis techniques, such as a finite element analysis and boundary element analysis, have been presented as an accurate tool for design and simulation of Switched Reluctance Motors, they do not give any method of a systematic design procedure with a minimum computational effort.

A neuro‐behavioural model of neophobia
Biological Reviews, EarlyView.ABSTRACT Fear can be defined as the internal neurological state that releases a repertoire of behaviours an animal performs to reduce the effect of an aversive factor. Neophobia, the fear of novelty, is a fundamental behavioural trait observed across a wide range of species from arthropods to humans.
