Virtual Park-based control strategy for grid-connected inverter interfaced renewable energy sources
(Inst Engineering Technology-Iet, 2019)
Unbalanced grid faults are the most severe perturbations which degrade the performance of grid-connected inverter interfaced renewable energy sources (IIRESs). In this regard, this study proposes a novel control strategy ...
Improving a battery charger architecture for electric vehicles with photovoltaic system
(Wiley, 2020)
In this study, a two-stage battery charger architecture with high-efficiency, multi-input, and output half-bridge LLC (HBLLC) resonance converter that performs a wide load range is proposed. The first input of the HBLLC ...
90° degrees Polarization rotator and antireflector using meanderline chiral metamaterials: Analytical and numerical approach
(Elsevier GmbH, 2015)
We demonstrate theoretically and numerically a chiral slab that can exhibit optical activity, circular dichroism, and antireflection in detail. Copolar and crosspolar transmitted and reflected waves depending on permittivity, ...
Linear Optical Absorption, Emission Properties and Ultrafast Carrier Dynamics of Aqua-chloro-bis(1,10-phenanthroline)manganese(II) 4-formylbenzoate Trihydrate
(Wiley, 2020)
In this study, the synthesis, Hirshfield surface analysis, linear absorption, fluorescence properties and carrier dynamics of [Mn(1,10-phenanthroline)(2)(H2O)Cl].(4-formylbenzoate)(H2O)(3) complex were reported. To determine ...
Experimental study on accelerometer-based ladle slag detection in continuous casting process
(Springer London, 2020)
The share of continuous casting method is increased day by day among steel production methods. In continuous casting plants, steel production is carried out using BOF (basic oxygen furnace) or EAF (electric arc furnace). ...
Gain-phase margins-based delay-dependent stability analysis of pitch control system of large wind turbines
(Sage Publications Ltd, 2019)
This paper investigates the effect of gain and phase margins (GPMs) on the delay-dependent stability analysis of the pitch control system (PCS) of large wind turbines (LWTs) with time delays. A frequency-domain based exact ...
Analysis of combined passively and actively morphing blade root chord length and blade taper for helicopter control
(Emerald Group Publishing Ltd, 2019)
Purpose The purpose of this study is to examine the effect of passive and active morphing of blade root chord length and blade taper on the control effort of the flight control system (FCS) of a helicopter. Design/method ...
Tunable energy harvesting on UHF bands especially for GSM frequencies
(Cambridge University Press, 2018)
Metamaterial-based energy harvesting structures operating at GSM goo and GSM 1800 frequency bands have been proposed. The basic structure is composed of four nested U-shaped elements on the front and back side of the ...
Effects of the actively morphing root chord and taper on helicopter energy
(Emerald Group Publishing Ltd, 2019)
Purpose The purpose of this paper presents the effects of actively morphing root chord and taper on the energy of the flight control system (i.e. FCS). Design/methodology/approach Via regarding previously mentioned purposes, ...
Improving Autonomous Performance of a Passive Morphing Fixed Wing UAV
(Kauno Technologijos Universitetas, 2020)
In this article, simultaneous longitudinal and lateral flight control systems design for both passive and active morphing unmanned aerial vehicles (UAVs) is first time applied for autonomous flight performance maximization. ...
