Switched Control and Tracking Application in Aeropendulum System using Fuzzy Models
(2021-07-11)
Switched robust controllers are presented and applied to an aeropendulum system made at the Control Research Laboratory from DEE-FEIS-UNESP in Brazil. The system has nonlinear dynamics and it is approximated by Takagi-Sugeno ...
Alterações em atributos químicos do solo pela aplicação de calcário na superfície ou incorporado
(2008-12-01)
The application of lime on the soil surface is necessary in some agricultural situations. The objective of this work was to verify changes in chemical attributes of a medium texture soil as a result of lime application ...
Base saturation in mixed substrate for seedlings of Eugenia uniflora and Eugenia involucrata
(Universidade Federal de Mato Grosso, 2018)
Contribuições ao projeto de controladores robustos a variações paramétricas aplicados a conversores conectados à rede
(Universidade Federal de Santa MariaBrasilEngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia ElétricaCentro de Tecnologia, 2021-05-12)
This Ph.D. thesis provides contributions to the design of robust current controllers
for grid-connected converters, including: i) a time-varying model to deal with the
magnetic soft saturation in the filter inductors and ...
Control mediante compensación de la saturación y de los filtros de detección de fallas
(Ciencia e Ingeniería, 2010)
An MOS transistor model for analog circuit design
(1998)
This paper presents a physically based model for the metal-oxide-semiconductor (MOS) transistor suitable for analysis and design of analog integrated circuits. Static and dynamic characteristics of the MOS field-effect ...
Surface applied lime dynamics and base saturation index in a consolidated no-tillage area
(2016-01-01)
The aim of this study was to evaluate the behavior of chemical properties and crop yields during five years after liming, in a consolidated no-tillage system area and indicate a base saturation index to serve as a criterion ...
MODE SATURATION, MODE COUPLING AND ENERGY HARVESTING FROM AMBIENT VIBRATION IN A PORTAL FRAME STRUCTURE
(Amer Soc Mechanical Engineers, 2014-01-01)
There has been much recent interest in the concepts of electro-mechanical systems that are able to scavenge, or harvest energy from their operating environment. Here, we present the extraction of energy from a simple portal ...
