“…In several practical applications, a zero-mean sinusoidal signal is not available; to deal with a dc offset, the traditional PLL and ANF methodologies are typically augmented heading towards a second-order generalized integrator-based orthogonal signal generator (OSG-SOGI) [9]. The OSG-SOGI architecture is also exploited in [10] and [11] to cope with the biased signal case, namely, in [11] the OSG-SOGI is extended to the thirdorder generalized integrator-based OSG (OSG-TOGI) that is characterized by an adaptive resonant frequency. Apart from the aforementioned methods, a number of nonlinear estimation algorithms employing suitable pre-filtering techniques also have been presented in literature to address the AFP estimation in presence of an unknown bias (see, for example, [12], [13], [14], [15], [16] and the references cited therein).…”

“…Зада-ча идентификации значительно усложняется в условиях реальных шумов измерений, которые могут привести к появлению смещения или осцилляции вокруг среднего значения оценки частоты. Таким образом, требуется разрабатывать методы повышения точности идентифика-ции частоты синусоидального сигнала в условиях шумов измерений.Известно множество подходов к решению задачи идентификации частоты [5][6][7][8][9][10]. Целью настоящей статьи является разработка метода повышения точности оценок, получае-мых при идентификации.…”
