Dynamic systems behaviour analysis and design based on the qualitative theory of differential equations: the Boost power converter case
(2015)
This paper uses the qualitative theory of differential equations to analyse/design the dynamic behaviour of control systems. In particular, the Poincaré compactification and the Poincaré--Hopf theorem are used for analysing ...
Mechanism and model of the oscillatory electro-oxidation of methanol
(AMER INST PHYSICS, 2010)
A mechanism for the kinetic instabilities observed in the galvanostatic electro-oxidation of methanol is suggested and a model developed. The model is investigated using stoichiometric network analysis as well as concepts ...
Study of degenerate bifurcations in maps: A feedback systems approach
(World Scientific, 2004-12)
The dynamical behavior of nonlinear maps undergoing degenerate period doubling or degenerate Hopf bifurcations is studied via a frequency-domain approach. The technique is based on a discrete-time feedback representation ...
Comportamento caótico em modelos matemáticos de câncer
(Universidade Estadual Paulista (Unesp), 2014-06-06)
In this work we study a system of ordinary differential equations which represent a mathematical model of cancer which has chaotic dynamics. In the study we use the bifurcation theory, especially the Hopf bifurcation and ...
