Editorial for the special issue on recent advances in adaptive methods for frequency estimation with applications

Abstract

SUMMARYThe Special Issue presents results of current research on adaptive methods designed for periodic signals with unknown frequency. The first group of papers presents new methods for parameter estimation, while the second group focuses on practical applications involving active noise and vibration control problems. These papers are compiled in a special virtual issue of the journal at the journal homepage. To access all of the papers please follow the following link

Identification of multi-sinusoidal signals with direct frequency estimation: An adaptive observer approach

“…The problem of determining the unknown amplitudes, frequencies and phases (AFP) of the components of a multi-sinusoidal signal represents a fundamental challenge in many engineering fields, including active noise and vibration control, periodic disturbance rejection, power quality monitoring, etc. (see, for instance the recent Special Issue [3] and the references cited therein).…”
