Simplification of the digital representation of the tent map through biased fixed point
M. Teixeira, N. P. Basilio, D. L. Firmo +2
Chaotic systems have been investigated in several areas of engineering. In control theory, such systems have instigated the emergence of new techniques as well, have been used as a…
Decimation analysis in the signal processing of current to detect broken bars in induction machine
J. S. Moreira, P. C. M. Lamim Filho, L. M. R. Baccarini +2
This paper presents a study on the reduction of the sampling frequency of the current signals of an induction motor, the reductions are performed by means time-decimation technique…
Interval Simulation of Narmax Models Based on Computer Arithmetic
P. F. S. Guedes, M. L. C. Peixoto, O. A. R. O. Freitas +3
System identification is an important area of science, which aims to describe the characteristics of the system, representing them by mathematical models. Since many of these model…
Synchronization on the accuracy of chaotic oscillators simulations
Gabriel H. A. Silva, Igor C. Silva, Wilson R. L. Junior +3
Numerical problems are considered on general synchronization of chaotic oscillators, through the evaluation of the Lower Bound Error index on two case studies: a Lorenz system unid…
A rigorous evaluation of the intermittence in the logistic map using lower bound error
Marcella N. R. Oliveira, Erivelton G. Nepomuceno
This article investigates the maximum time of simulation in which the phenomenon of the intermittence can be observed with numerical confidence in discrete maps. Interval analysis…
Note on improvement precision of recursive function simulation in floating point standard
Melanie R. Silva, Erivelton G. Nepomuceno, Samir A. M. Martins
An improvement on precision of recursive function simulation in IEEE floating point standard is presented. It is shown that the average of rounding towards negative infinite and ro…
