A comparison of quadratic TFDs for entropy based detection of components time supports in multicomponent nonstationary signal mixtures
(
IEEE
, 2013 , Conference Paper)
Separation of different signal components, produced by one or more sources, is a problem encountered in many signal processing applications. This paper proposes a fully automatic undetermined blind source separation method, ...
Iterated unscented Kalman filter-based maximum power point tracking for photovoltaic applications
(2013 , Conference Paper)
One of main challenges in harvesting power from a PV source is maximum power point tracking (MPPT). This is due to the nonlinear behaviour and characteristics of PV arrays. Conventional MPPT techniques usually utilize a ...
An IV-SVM-based approach for identification of state-space LPV models under generic noise conditions
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
This paper presents a nonparametric identification method for state-space linear parameter-varying (LPV) models using a modified support vector machine (SVM) approach. While most LPV identification schemes in the state-space ...
