A method for analysis of harmonics and inter-harmonics
48th Midwest Symposium on Circuits and Systems, 2005., 2005A method for analysis of signals containing harmonics and inter-harmonics is presented and discussed. This method is primarily developed for analysis of power system signals which contain harmonic and inter-harmonic components. However, usefulness of the proposed technique goes beyond the area of power systems and it can be employed for other ...

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.

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 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].

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 ...
