Lyapunov Stability Criteria For Reacting Ionic Fluid Flows
(Springher-Verlag BerlinBerlin, 2016)
Modelo matemático para a melhoria da estabilidade transitória de sistemas elétricos de potência baseado na mudança estrutural do sistema de transmissão
(Universidade Estadual Paulista (Unesp), 2019-02-08)
Apresenta-se um modelo matemático, baseado na análise de sensibilidade, para a realização de controle de segurança dinâmica para a melhoria da estabilidade transitória de sistemas elétricos de potência. O controle de ...
Redes neurais recorrentes e expoente de Lyapunov aplicados a séries temporais financeiras
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Elétrica e Informática IndustrialUTFPR, 2019-08-29)
The study of financial market asset pricing is considered one of the most relevant subjects in this segment. The possibility to obtain profit during the intraday oscillations turned the predictability problem relevant to ...
Short Lyapunov time: a method for identifying confined chaos
(Edp Sciences S A, 2014)
Variable-Structure Control Design of Switched Systems With an Application to a DC-DC Power Converter
(Institute of Electrical and Electronics Engineers (IEEE), 2009-09-01)
This paper is concerned with the design of state-feedback variable-structure controllers (VSCs) for a class of continuous-time switched plants. In particular, a new VSC design method based on Lyapunov-Metzler (LM) inequalities ...

Lyapunov functions for fractional order systems
(Elsevier, 2014)
A new lemma for the Caputo fractional derivatives, when 0 < a < 1, is proposed in this
paper. This result has proved to be useful in order to apply the fractional-order extension
of Lyapunov direct method, to demonstrate ...
Nonsmooth Lyapunov pairs for infinite-dimensional first-order differential inclusions
(PERGAMON-ELSEVIER SCIENCE LTD, 2012-02)
The main objective of this paper is to provide new explicit criteria to characterize weak lower semicontinuous Lyapunov pairs or functions associated to first-order differential inclusions in Hilbert spaces. These inclusions ...
Continuous random field representation of stochastic moving loads
(2022)
While the problem of random loads moving across a beam has been studied extensively, the existing methods are limited in terms of their applicability. The most common approach uses modal superposition, which requires that ...
