Enabling Variable Phase-Pole Drives With the Harmonic Plane Decomposition

IEEE Access
Magnet-free acrlongpl vppm are competitive alternatives in electric vehicles where torque-speed operating region, reliability, cost, and energy efficiency are key metrics. However, their modeling and control have so far relied on existing fixed-phase and

Plane-wave decomposition and randomised training; a novel path to generalised physics-informed neural networks for simple harmonic motion

Machine Learning: Science and Technology
In this paper, we introduce a formulation of physics-informed neural networks (PINNs), based on learning the form of the Fourier decomposition, and a training methodology based on a spread of randomly chosen boundary conditions.

Harmonic Plane Decomposition: An Extension of the Vector-Space Decomposition - Part I

IECON 2020 The 46th Annual Conference of the IEEE Industrial Electronics Society, 2020
In this paper the harmonic plane decomposition from part I is completed. Multiphase electrical machines with independently controlled stator coils benefit from a fixed amount of current controllers and unified models. In part I, the foundation for such models was laid. This paper shows that the choice of the base case has to fulfill certain criteria to

Electromagnetic Scattering from a Graphene Disk: Helmholtz-Galerkin Technique and Surface Plasmon Resonances

Mathematics, 2021
The surface plasmon resonances of a monolayer graphene disk, excited by an impinging plane wave, are studied by means of an analytical-numerical technique based on the Helmholtz decomposition and the Galerkin method.

Detection of Multiple Open Faults in Variable Phase-Pole Machines based on Harmonic Plane Decomposition

2023 IEEE 14th International Symposium on Diagnostics for Electrical Machines, Power Electronics and Drives (SDEMPED), 2023
Multiphase electrical machine are inherently truefault tolerant, which is a key difference as compared to conventionalthree-phase machines. The subgroup of variable phase-polemachines have the ability to change phase-pole configurationsonly through current control.

Denoising Directional Room Impulse Responses with Spatially Anisotropic Late Reverberation Tails

Applied Sciences, 2020
Directional room impulse responses (DRIR) measured with spherical microphone arrays (SMA) enable the reproduction of room reverberation effects on three-dimensional surround-sound systems (e.g., Higher-Order Ambisonics) through multichannel convolution ...

Reflection Identities of Harmonic Sums of Weight Four

Universe, 2019
In attempt to find a proper space of function expressing the eigenvalue of the color-singlet BFKL equation in N = 4 SYM, we consider an analytic continuation of harmonic sums from positive even integer values of the argument to the complex plane.

A Unified Formulation of Radiative Transfer in Plane-Parallel Atmospheres Based on General Decomposition of Radiance. Part II: An Exemplifying Application to the Hemispherical Harmonics Method with Four Components [PDF]

Journal of the Atmospheric Sciences, 2017
Abstract Based on the unified formulation, the so-called hemispherical harmonics method with four components (HSHM4) is derived following the general procedure described in the first paper of this series. The numerical results of this method, including the flux reflections, transmissions, and absorptions for different optical depths ...
