Controle robusto H∞ por meio de LMIS aplicado a conversores conectados
(Universidade Federal de Santa Maria, 2019-12-16)
This work presents a robust current control for grid-connected converters subject
to uncertain parameters in the grid impedance. Specifically, a voltage source inverter is
connected by means of an LCL filter to a ...
Análise e controle de aerogeradores com conversor pleno durante afundamentos de tensão
(Universidade Federal de Santa Maria, 2012-09-28)
This thesis addresses the main issues regarding the operation of full power converters
wind turbines connected to the grid under balanced and unbalanced voltage sags.
In the past, the grid codes allowed wind turbines to ...
Controle adaptativo de corrente aplicado a conversores estáticos conectados à rede elétrica
(Universidade Federal de Santa Maria, 2013-02-28)
This thesis addresses the design of adaptive current controllers applied for voltagesource
grid-connected converters with LCL-filter. Due to the grid equivalent impedance
uncertainty and/or variation at the point of ...
