The Bellman Function Technique in Harmonic Analysis
, 2020The Bellman function, a powerful tool originating in control theory, can be used successfully in a large class of difficult harmonic analysis problems and has produced some notable results over the last thirty years.

Analysis and Control of Current Harmonic in IPMSM Field-Oriented Control System
IEEE transactions on power electronics, 2022There is a certain amount of current harmonics in interior permanent magnet synchronous motor. In order to accurately control the current harmonic, this article focuses on three aspects: establishing current harmonic calculation model, extracting current

Stereopsis by harmonic analysis
Vision Research, 1979Abstract Stereoscopically viewed vertical gratings whose cycle widths differ by 10% fuse into a single grating rotated in depth. The perceived tilt can be predicted on the basis of a barwise computation of geometrical disparities, or on the basis of a comparison in terms of harmonic content.

Harmonic Analysis on Semigroups
The Annals of Mathematics, 1983wherever t > 0 and 1 < p < so. E. M. Stein [St 3] developed a "LittlewoodPaley" theory for such semigroups, with some additional hypotheses. R. R. Coifman, R. Rochberg, and G. Weiss [CRW] pointed out that some of Stein's estimates could be obtained more simply by the use of "transference" techniques which were developed by Coifman and Weiss [CW].

Dyadic Harmonic Analysis and Weighted Inequalities: The Sparse Revolution
New Trends in Applied Harmonic Analysis, Volume 2, 2018We will introduce the basics of dyadic harmonic analysis and how it can be used to obtain weighted estimates for classical Calderon–Zygmund singular integral operators and their commutators.

Journal of Applied Mechanics, 1935
Abstract The method of harmonic analysis described in this paper is of the selected ordinate type. It is similar to the Fischer Hinnen analysis in that a different spacing of ordinates is used for each harmonic component to be determined, and no multiplications are necessary. The basis of derivation is the assumption that the curve to be

Harmonic Stability Analysis of MMC-Based DC System Using DC Impedance Model
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2020The dc impedance model of a modular multilevel converter (MMC) is the basis for analyzing harmonic resonances of MMC-based dc systems. As an MMC typifies a multiple harmonic response system, its internal dynamics and controls significantly influence its ...

Modeling and Stability Analysis of Inverter-Based Microgrid Under Harmonic Conditions
IEEE Transactions on Smart Grid, 2020Microgrids (MGs) operate under harmonic conditions due to the integration of nonlinear loads. The autonomous harmonic compensation control of inverter-interfaced DG has been proposed to successfully mitigate the harmonics.
