Embedding of nonlinear systems in a linear parameter-varying representation
(
IFAC Secretariat
, 2014 , Conference Paper)
This paper introduces a systematic approach to synthesize linear parameter-varying (LPV) representations of nonlinear (NL) systems which are originally defined by control affine state-space representations. The conversion ...
A permanent-magnet machine with improved torque density based on a single layer winding layout for electric vehicle applications
(
IEEE
, 2014 , Conference Paper)
This paper proposes a novel single layer winding layout for a permanent magnet machine with improved torque density for electric vehicle applications. In this paper, two permanent-magnet (PM) machines with outer rotors and ...
Investigation of sensorless capacitor voltage balancing technique for modular multilevel converters
(
IEEE
, 2014 , Conference Paper)
Modular Multilevel converters (MMC) have become one of the most promising topologies for DC-AC conversion in recent years. Capacitor voltage balancing is a vital issue for proper operation of the MMC. Generally, conventional ...
Resources allocation for large-scale dynamic spectrum access system using particle filtering
(
IEEE
, 2014 , Conference Paper)
This paper proposes an efficient spectrum and power allocation solution for a large scale dynamic spectrum access (DSA) systems. Unlike conventional methods relying on optimization techniques which need huge computational ...
Multiple antenna cyclostationary-based detection of primary users with multiple cyclic frequency in Cognitive Radios
(
IEEE
, 2014 , Conference Paper)
In this paper, we study the problem of multiple antenna spectrum sensing by using cyclostationary features of Primary Users (PUs) signals in Cognitive Radios (CRs). We consider the general case of multiple antenna sensing ...
A general multicompartment lung mechanics model with nonlinear resistance and compliance respiratory parameters
(
IEEE
, 2014 , Conference Paper)
In this paper, we develop a nonlinear multicompartment lung mechanics model that accounts for nonlinearities in both the airway resistances and the lung compliances. Many models assume that the airway resistances for a ...
Hybrid underlay/overlay cognitive radio system with hierarchical modulation in the presence of channel estimation error
(
IEEE
, 2014 , Conference Paper)
In this paper, we study the performance of hybrid cognitive radio (CR) system in the presence of channel estimation error (CER) in terms of bit-error-probability (BEP) and outage probability. We assume simultaneous switching ...
Open and closed-loop motor control system with incipient broken rotor bar fault detection using current signature
(
IEEE
, 2014 , Conference Paper)
Motor drive system is considered the most important asset in industrial applications. Detection of broken rotor bars has long been important but difficult job in detection area of incipient motor faults. The need for highly ...
An LCL filter-based grid-interfaced three-phase voltage source inverter: Performance evaluation and stability anaylsis
(
Institution of Engineering and Technology
, 2014 , Conference Paper)
Power converters in grid connection applications commonly employ Sinusoidal Pulse-Width Modulation (SPWM) technique. Passive filters are employed in order to attenuate the generated switching current ripples and reduces ...
Robust Hybrid EKF approach for state estimation in multi-scale nonlinear singularly perturbed systems
(
IEEE
, 2014 , Conference Paper)
In this paper a general framework is developed for state estimation in a class of nonlinear continuous-time singularly perturbed systems. Our approach is based on the hybrid extended Kalman filter in which observations are ...
