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, ...
Editorial: Time frequency and array processing of non-stationary signals
(
Springer
, 2012 , Article)
Conventional time-frequency analysis methods were extended to data arrays in many applications, and there is the potential for more synergistic development of new advanced tools by exploiting the joint properties of ...
Theoretical accuracy analysis of indoor visible light communication positioning system based on time-of-arrival
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
In this paper, an improved channel model and estimation for positioning in indoor environments using the visible light is presented. For positioning, the specific propagation and indoor channel model for visible light is ...

Sensorless V/f control with MRAS speed estimator for a five-phase induction machine under open-circuit phase faults
(
IEEE
, 2013 , Conference Paper)
This paper introduces a sensorless scalar controller with MRAS speed estimator based on simple Proportional Resonant PR controllers to provide a disturbance-free operation to a five-phase induction machine under phase open ...
Sensorless field oriented control of five-phase induction machine under open-circuit phase faults
(
IEEE
, 2013 , Conference Paper)
Recently, multiphase machine is promoted to replace three-phase drives in high power safety-critical applications. Among the numerous advantages of multiphase induction machine drives, operation and self-starting under ...
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 ...
Single sensor three-phase permanent magnet synchronous motor drive based on Luenberger style-observers
(
IEEE
, 2012 , Conference Paper)
This paper presents a technique to estimate phase currents and rotor position in a vector-controlled PMSM drive using only dc-link current measurement. Three cascaded Luenberger style observers were used to perform this ...
Rotor Flux-Oriented Control of Three-Phase Induction Motor Using Sliding Mode Controller and Rotor Flux Estimator
(
Springer Science and Business Media Deutschland GmbH
, 2021 , Conference Paper)
The work focuses on implementing rotor flux-oriented control (RFOC) for controlling the rotational speed and torque of a three-phase squirrel cage induction motor (IM). The speed controller has been implemented based on ...
A novel particle filter parameter prediction scheme for failure prognosis
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
Particle filters are well-known as powerful tools for accomplishing state and parameter estimation and their propagation prediction in nonlinear dynamical systems. Their ability to include system model parameters as part ...
