A family of gradient descent grid frequency estimators for the SOGI filter

, 2017
This paper applies the adaptive gradient descent method to the second-order generalized integrator (SOGI) filter in order to find an online estimation algorithm for the grid frequency, which leads to the proposal of three possible estimators. One of them

A new LPF-based grid frequency estimation for the SOGI filter with improved harmonic rejection [PDF]

, 2018
This paper proposes a new method for the estimation of the grid voltage frequency using a low-pass filter (LPF) approach. The estimated frequency is used to tune a second order generalized integrator (SOGI) filter commonly used for grid monitoring ...

A Frequency Locked-Loop with Reduced Tuning Complexity for Single-Phase Grid-Tied System with Inherent DC-Offset Rejection Capability

To ensure the high performance of grid-connected systems, a synchronization unit plays a crucial role. The frequency-locked loop (FLL) has gained popularity for the synchronization and control of grid-tied converters in recent times.
