Enhance OF SOGI-FLL and SOGI-PLL response to voltage sags and swells perturbations [PDF]

open access: yes, 2023
The scope of this thesis is related to the enhancement of the operation of distributed generators (DGs) based on renewable energies (REs) when connected to the conventional grid network. Synchronization of those DGs, i.e. their front-end inverters, with the grid is critical for injecting power into the grid.

Experimental implementation of low-cost and robust sensorless control based on SOGI-FLL estimator for electric vehicles

open access: yesInternational Journal of Power Electronics and Drive Systems (IJPEDS), 2022
Sensorless control techniques of electric motor dedicated to electric vehicles (EVs) offer low-cost and high operating performance. In this paper, a low-cost and robust speed-sensorless control scheme based on a second-order generalized integrator-frequency-locked loop method (SOGI-FLL) is proposed with only one current sensor.

A New THD Measurement Method With Small Computational Burden Using a SOGI-FLL Grid Monitoring System [PDF]

open access: yesIEEE Transactions on Power Electronics, 2020
This article proposes a new method for obtaining the total harmonic distortion (THD) using few math operations, a low-pass filter (LPF), and a grid monitoring system able to provide the fundamental and harmonics components of the grid voltage. The method is particularly developed by using the second-order generalized integrator (SOGI) error signal ...

The Study of SRM Sensorless Control Strategy Based on SOGI-FLL and ADRC-PLL Hybrid Algorithm

open access: yesElectronics, 2023
The inductance model used in traditional sensorless control methods for switched reluctance machines (SRMs) exhibits high-order harmonics. The precision of the motor may be impacted by the buildup of rotor estimate errors caused by these harmonics.
