Abstract in Portuguese
Neste trabalho, duas técnicas de controle robusto (LQG/LTR e DML), aplicadas a um sistema elétrico de potência, são avaliadas através dos raios de estabilidade do sistema. As incertezas estruturadas do modelo nominal são consideradas nos dois controladores. Um conjunto de modelos é gerado considerando as combinações das incertezas paramétricas. Os valores singulares estruturados dos dois sistemas de controle são analisados.

Abstract in English
In this work, two techniques of robust control (LQG/LTR) and LMI), applied to a power electric system, are available via stability radii of the system. The structured uncertainties of the nominal model are considered in both designs. A set of models is generated considering the combinations of the parametric uncertainties. The structured singular values of both systems are analysed.
