Stability analysis for the Chua circuit with cubic polynomial nonlinearity based on root locus technique and describing function method
(2020-12-01)
This work investigates the dynamics of the Chua circuit with cubic polynomial nonlinearity using methods for stability analysis based on linearization and frequency response. Root locus technique maps eigenvalues of the ...
A Simple Method for Impasse Points Detection in Nonlinear Electrical Circuits
(Hindawi Publishing Corporation, 2018-03)
In a nonlinear system, impasse points are singularities beyond which solutions are not continuable. In this article, we study two families of nonlinear electrical circuits, which can be represented by nonlinear Implicit ...
One-port nonlinear electric circuit for simulating grounding systems under impulse current
(Elsevier B.V., 2016-01-01)
A one-port nonlinear electric circuit to simulate grounding systems behaviors under high impulse currents is presented. The circuit is based on Loboda's and Pochanke's equations, which describe nonlinear behaviors of soil ...
Allocation of protective devices in distribution circuits using nonlinear programming models and genetic algorithms
(Elsevier B.V., 2004-04-01)
The optimized allocation of protective devices in strategic points of the circuit improves the quality of the energy supply and the system reliability index. This paper presents a nonlinear integer programming (NLIP) model ...
Experimental characterization of nonlinear systems: a real-time evaluation of the analogous Chua`s circuit behavior
(SPRINGER, 2010)
This paper presents an experimental characterization of the behavior of an analogous version of the Chua`s circuit. The electronic circuit signals are captured using a data acquisition board (DAQ) and processed using LabVIEW ...
Comparative analysis for reactive energy measurement methodologies, under non-sinusoidal conditions in three-phase four-wire circuits
(2011-12-28)
This paper presents some methodologies for reactive energy measurement, considering three modern power theories that are suitable for three-phase four-wire non-sinusoidal and unbalanced circuits. The theories were applied ...
Integrated circuit implementation of multi-dimensional piecewise-linear functions
(Academic Press Inc Elsevier Science, 2010-12)
In this paper we present an integrated circuit implementing piecewise-linear (PWL) functions with three inputs, where each input can be either analog or digital. The PWL function to be implemented can be chosen by properly ...
Harmonic propagation analysis in electric energy distribution systems
(2011-12-01)
An important alteration of the equivalent loads profile has been observed in the electrical energy distribution systems, for the last years. Such fact is due to the significant increment of the electronic processors of ...
