Setting the preheating process of electronic ballasts for hot-cathode fluorescent lamps, considering the Rh/Rc ratio
(2006-12-01)
This paper presents a new model for the representation of the electrodes filaments of fluorescent lamps, during their preheating, and an analysis capable to guide the design of the preheating process in electronic ballasts. ...
Comparative analysis of synchronization algorithms based on PLL, RDFT and Kalman Filter
(2007-12-01)
This paper discusses the main characteristics and presents a comparative analysis of three synchronization algorithms based respectively, on a Phase-Locked Loop, a Kalman Filter and a Discrete Fourier Transform. It will ...
Practical comparisons among electronic energy meters, a precision energy meter and IEEE1459 for reactive energy measurements, under unbalanced and non-sinusoidal conditions
(2012-12-01)
This paper presents a practical experimentation for comparing reactive/non-active energy measures, considering three-phase four-wire non-sinusoidal and unbalanced circuits, involving five different commercial electronic ...
Computational tool to support design of DAC Converter model AD7528 with the object code in XML
(2012-12-01)
Based on literature review, electronic systems design employ largely top-down methodology. The top-down methodology is vital for success in the synthesis and implementation of electronic systems. In this context, this paper ...
Proposal of a dedicated telemetry device for real-time and remote measurements
(2011-09-05)
This work aims to demonstrate an application of telemetry for monitoring process variables. The authors developed the prototype of a dedicated device capable of multiplexing, encoding and transmitting real-time data signals ...
A neural networks-based method for single-phase harmonic content identification
(2008-12-01)
A neural method is presented in this paper to identify the harmonic components of an ac controller. The components are identified by analyzing the single-phase current waveform. The method effectiveness is verified by ...
Evaluation of MPPT techniques for photovoltaic applications
(2011-09-21)
This paper presents a careful evaluation among the most usual MPPT (Maximum Power Point Tracking) techniques, doing meaningful comparisons with respect to the amount of energy extracted from the photovoltaic (PV) panel, ...
Controlling traffic jams on urban roads modeled in Coloured Petri net using Genetic Algorithm
(2012-12-01)
This paper presents an application to traffic lights control in congested urban traffic, in real time, taking as input the position and route of the vehicles in the involved areas. This data is obtained from the communication ...
Discrete-time sliding mode control of input-delay systems applied on a power generation system
(2006-12-01)
This paper presents two discrete sliding mode control (SMC) design. The first one is a discrete-time SMC design that doesn't take into account the time-delay. The second one is a discrete-time SMC design, which takes in ...
Nonlinear Control Strategy based on Discrete-Time State Dependent Riccati Equation for Electronic Throttle Control
(Ieee, 2016-01-01)
This paper aims to present a new control strategy for eletronic throttle control (ETC) used for the acceleration function in a vehicle. Firstly, an analitical model describing is developed with the purpose to evaluation ...
