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, ...
Development of a Virtual Learning Module Using Graphic Interface for Remote Teaching of Photovoltaic Systems
(2021-01-10)
In this research, a Graphical User Interface (GUI) was developed to assist in the virtual teaching of photovoltaic systems. This GUI allows friendly and sequential interaction between the user (student) and the latent ...
The use of tuned filters as an attenuator device of harmonics generated by multipulse converters
(2011-05-31)
The purpose of this paper is to present a computer model that enables the operation analysis of a tuned filter as an attenuator device of harmonic generated 12 and 18-pulses converters with Y-generalized differential ...
Robust control applications for smart truss structure
(2005-12-01)
A finite element modeling of an intelligent truss structure with piezoelectric stack actuators for the purpose of active damping and structural vibration attenuation is presented. This paper concerns with the following ...
Fuzzy logic to predict thermal damages of ground parts
(2010-07-20)
One of the critical problems in implementing an intelligent grinding process is the automatic detection of workpiece surface burn. This work uses fuzzy logic as a tool to classify and predict burn levels in the grinding ...
Implementation of filters for image pre-processing for leaf analyses in plantations
(2008-07-28)
In this work an image pre-processing module has been developed to extract quantitative information from plantation images with various degrees of infestation. Four filters comprise this module: the first one acts on ...
A Simple maxwell Based Model in Order to Represent the frequency-dependent viscosity measured by ultrasound
(2008-12-01)
A previous work showed that viscosity values measured high frequency by ultrasound agreed with the values at low frequency by the rotational viscometer when conditions are met, such as relatively low frequency viscosity. ...
Computer tools to aid the learning and design steps for photovoltaic systems
(2011-12-28)
This paper presents novel simulation tools to assist the lecturers about learning processes on renewable energy sources, considering photovoltaic (PV) systems. The PV behavior, functionality and its interaction with power ...
