Controle chaveado e chaveado suave de sistemas não lineares incertos via modelos fuzzy T-S
(Universidade Estadual Paulista (Unesp), 2017-12-14)
O controle chaveado pode ser eficientemente utilizado no controle de sistemas fuzzy TakagiSugeno (T-S) incertos, que possuam funções de pertinência incertas e modelos locais conhecidos. Como estes sistemas fuzzy podem ...
Comparative analysis of performance of switching control techniques running on digital devices.
(2015-05-22)
This work shows the implementation of switching control techniques on programmable devices, in order to improve the performance of a speed DC-motor system under the action of load disturbances. Two main techniques, namely: ...

Estudo da estabilidade de um conversor buck com filtro de entrada considerando a análise de impedâncias
(Universidade Federal de Santa MariaBrasilUFSMCentro de Tecnologia, 2018-12-13)
A switching converter which has effective output voltage control operates as a constant
power load and behaves as a negative impedance. When an input filter is connected
to the converter to smooth the absorbed current ...
Autophagy mediates tumor necrosis factor-alpha-induced phenotype switching in vascular smooth muscle A7r5 cell line
(Public library science, 2018)
Vascular smooth muscle cells (VSMC) dedifferentiation from a contractile to a synthetic phenotype contributes to atherosclerosis. Atherosclerotic tissue has a chronic inflammatory component with high levels of tumor necrosis ...
