Capacitor voltage balancing using redundant states of space vector modulation for five-level diode clamped inverters
( IEEE , 2010 , Article)A redundancy balancing technique for the five-level diode-clamped inverter is presented, which balances the four dc-link capacitor voltages at high modulation index and high power factor. The technique is based on dividing ... -
Cluster validity index based on n-sphere
( IEEE , 2014 , Conference Paper)In this paper, we propose a new cluster validity index (CVI) based on geometrical shape. Classic CVIs are based on a combination of separation and compactness measures and may include a measure of overlap between clusters. ... -
Compressed wideband spectrum sensing with correlated subband occupancy in multi-antenna cognitive radios
(2012 , Conference Paper)In this paper, we investigate the use of multiple antennas at the cognitive radio receiver for improved wideband spectrum sensing and exploit compressed sensing to reduce the extremely high sampling rate of wideband signal. ... -
DC-link capacitor voltage balancing for a five-level diode-clamped active power filter using redundant vectors
(2013 , Article)This paper investigates the compensation and modulation processes of the five- level diode-clamped active power filter, compensating a three-phase rectified resistor-inductor load with redundant vectors. From the analysis, ... -
Evaluation of a multilevel cascaded-type dynamic voltage restorer employing discontinuous space vector modulation
( IEEE Industrial Electronics Society , 2010 , Article)In this paper, the application of a cascaded multilevel inverter as a dynamic voltage restorer (DVR) is investigated. Two discontinuous multilevel space vector modulation (SVM) techniques are implemented for DVR control ... -
Fault detection and isolation of two-dimensional (2D) systems
( Elsevier B.V. , 2017 , Article)In this work, we develop a novel fault detection and isolation (FDI) scheme for discrete-time two-dimensional (2D) systems that are represented by the Fornasini?Marchesini model II (FMII). This is accomplished by generalizing ... -
Grid integration of multiple wind turbines using a multi-port converter - A novel simultaneous space vector modulation
( Elsevier Ltd , 2022 , Article)In this paper, an innovative approach of integrating multiple doubly-fed induction generator (DFIG)-based wind turbines using a single multi-port converter unit, named as a unified expandable power converter (UEPC) is ... -
K-Subspaces Quantization for Approximate Nearest Neighbor Search
( IEEE Computer Society , 2016 , Article)Approximate Nearest Neighbor (ANN) search has become a popular approach for performing fast and efficient retrieval on very large-scale datasets in recent years, as the size and dimension of data grow continuously. In this ... -
Matlab/Simulink Modeling and Simulation of Electric Appliances Based on their Actual Current Waveforms
( Institute of Electrical and Electronics Engineers Inc. , 2019 , Conference Paper)This paper presents a novel modeling technique of electric appliances using Matlab/Simulink based on their actual measured current waveforms. Home appliances were used as the study case, but the proposed approach can be ... -
Rate Control for RIS-Empowered Multi-Cell Dual-Connectivity HetNets: A Distributed Multi-Task DRL Approach
( IEEE , 2024 , Article)Heterogeneous wireless networks (HetNets), where networks are deployed with ultra-dense small cells (SCs), is one of the main enabling technologies for future wireless networks. In such networks, signals are vulnerable to ... -
Vector control of multiphase induction machine under open-circuit phase faults
( IEEE Computer SocietyIEEE , 2013 , Conference Paper)Multiphase induction machine is normally controlled using rotor field oriented vector control. Under phase(s) loss, the machine currents can be optimally controlled to satisfy certain optimization criteria. In this paper, ...
