Improving the tracking capability of adaptive filters via convex combination
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2008)
As is well known, Hessian-based adaptive filters (such as the recursive-least squares algorithm (RLS) for supervised adaptive filtering, or the Shalvi-Weinstein algorithm (SWA) for blind equalization) converge much faster ...
Stochastic stability analysis for the constant-modulus algorithm
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2008)
We derive an easy-to-compute approximate bound for the range of step-sizes for which the constant-modulus algorithm (CMA) will remain stable if initialized close to a minimum of the CM cost function. Our model highlights ...
Control of a Thermal Airflow Process - Part I: System Identification
(Universidade Tecnológica Federal do Paraná (UTFPR), 2017)
Dynamic Characterization and Equalization of a Power Line Communication Channel
(Institute of Electrical and Electronics Engineers, 2013-12)
Power Line Communication (PLC) systems need signal processing algorithms in order to recover the transmitted signals from the high degrading medium. In the literature exist some techniques that work on the basis of a ...
Adaptive quasi-sliding mode control based on a recursive weighted least square estimator for a DC motor
(INSTITUTE OF ELECTRICAL AND ELECTRONICS ENGINEERS INC., 2016-09-19)
This paper presents the methodology of design of a discrete-time adaptive quasi-sliding mode controller (QSMC) based on a recursive weighted least square (RWLS) estimator for a dc motor. The proposed control scheme allows ...
Adaptive filter feature identification for structural health monitoring in aeronautical panel
(2011-08-15)
This paper presents an approach for structural health monitoring (SHM) by using adaptive filters. The experimental signals from different structural conditions provided by piezoelectric actuators/sensors bonded in the test ...
New Issues On The Numerical Stability Of The Fast Recursive Least Squares Algorithm
(IEEE, Piscataway, NJ, United States, 1995)
An Array Recursive Least-Squares Algorithm With Generic Nonfading Regularization Matrix
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2010)
We present a novel array RLS algorithm with forgetting factor that circumvents the problem of fading regularization, inherent to the standard exponentially-weighted RLS, by allowing for time-varying regularization matrices ...
Um controlador adaptativo robusto aplicado a conversores estáticos conectados à rede elétrica através de filtro LCL
(Universidade Federal de Santa MariaBREngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia Elétrica, 2014-08-26)
This Thesis deals with the development of a novel robust model reference adaptive
controller (RMRAC), in discrete-time applied to grid-connected systems using LCL
filter. This controller uses a modified robust parameters ...
Determinação de órbitas com o GPS através de mínimos quadrados recursivo com rotações de Givens
(Universidade Estadual Paulista (Unesp), 2001)
O Sistema de Posicionamento Global oferece um poderoso e relativamente barato processo para se determinar órbitas de satélites artificiais da Terra. Este trabalho apresenta um método de determinação de órbita para satélites ...
