Four new applications of Second-Order Generalized Integrator Quadrature Signal Generator
2016 IEEE Applied Power Electronics Conference and Exposition (APEC), 2016 The Second-Order Generalized Integrator (SOGI) was used as a building block for the SOGI-Quadrature-Signal Generator (SOGI-QSG) which has been widely used for gridsynchronization, frequency estimation, and harmonic extraction over the past decade.

Non Adaptive Second-Order Generalized Integrator for Identification of a Biased Sinusoidal Signal
IEEE Transactions on Automatic Control, 2012This note presents a new algorithm that is designed to identify the frequency, magnitude, phase and offset of a biased sinusoidal signal. The structure of the algorithm includes an orthogonal system generator based on a second-order generalized integrator.

An Improved Integrator Discretization Method for Multiple Second-Order Generalized Integrators
2021 IEEE 4th International Electrical and Energy Conference (CIEEC), 2021Multiple second-order generalized integrators (MSOGI) can extract fundamental waves, harmonics and their orthogonal components in real time, which plays a vital role in power quality assessment, grid synchronization, harmonic compensation and other aspects. Different discretization methods of MSOGI determine the complexity of its implementation and the

A Novel Discretization Method for Multiple Second-Order Generalized Integrators
IEEE Transactions on Power Electronics, 2021Multiple second-order generalized integrators (MSOGI) has been widely used to extract the signal that contains multiple harmonics. The MSOGI needs to be implemented in the discrete-time domain for its practical applications. More critically, the discretization method can greatly affect its performance.

Some second-order integral inequalities of generalized Hardy type
Proceedings of the Royal Society of Edinburgh: Section A Mathematics, 1999A uniform method of obtaining various types of integral inequalities involving a function and its first derivative is extended to integral inequalities involving a function and its second derivative. Specifically, some quadratic integral inequalities of generalized Hardy type involving a function and its second derivative are derived and examined.
