Experimental Validation of Novel Stationary Frame Selective Harmonic Extraction Strategy
نویسندگان
چکیده
This paper presents a novel stationary frame selective harmonic extraction strategy. Compared with the widely used methods based on the instantaneous power theory, it only needs one matrix transformation, which significantly reduces the computational burden. Time-domain simulation in the MATLAB/Simulink and experimental results based on the 32-bit fixed-point TMS320F2812 DSP platforms verify the effectiveness of the proposed method. Streszczenie. W artykule zaprezentowano uproszczoną metodę ekstrakcji harmonicznych. W porównaniu z ogólnie stosowaną metoda bazująca na teorii mocy chwilowej proponowana metoda wymaga tylko przekształcenia macierzy co znacznie redukuje obciążenie komputera. (Eksperymentalna weryfikacja nowej metody selektywnej ekstrakcji harmonicznych)

Pitch Estimation Based on Long Frame Harmonic Model and Short Frame Average Correlation Coefficient
We propose a pitch estimation method based on long frame harmonic model (LFHM) and short frame average correlation coefficient (SFACC). The long frame used here is three times as long as the short frame. Our approach consists of two main steps: pitch candidates extraction based on LFHM, and final pitch selection based on the SFACC. The long frame analysis for speech signal is able to achieve a ...
متن کاملA Closed-Loop Selective Harmonic Compensation for Active Filters
This paper proposes a control algorithm for parallel active power filters, based on current-controlled pulsewidth-modulated converters, which allows precise compensation of selected harmonic currents produced by distorting loads. The approach is based on the measurement of line currents and performs the compensation of the selected harmonics using closed-loop synchronous frame controllers. Than...

This paper presents modeling, simulation and control of matrix converter (MC) for variable speed wind turbine (VSWT) system including permanent magnet synchronous generator (PMSG). At a given wind velocity, the power available from a wind turbine is a function of its shaft speed. In order to track maximum power, the MC adjusts the PMSG shaft speed.The proposed control system allowing independen...
متن کاملNovel Atom-Type-Based Topological Descriptors for Simultaneous Prediction of Gas Chromatographic Retention Indices of Saturated Alcohols on Different Stationary Phases
In this work, novel atom-type-based topological indices, named AT indices, were presented as descriptors to encode structural information of a molecule at the atomic level. The descriptors were successfully used for simultaneous quantitative structure-retention relationship (QSRR) modeling of saturated alcohols on different stationary phases (SE-30, OV-3, OV-7, OV-11, OV-17 and OV-25). At first...
