It is assumed that the plant has the number of outputs greater than the number of inputs. Some sufficient conditions for the solution of the problem are presented and compared. These results can be directly applied in the LMI-based design of Variable Structure Control (VSC) of uncertain plants. ©2008 IEEE.130-135engControl theoryFeedbackLinear control systemsMatrix algebraSpectrum analyzersComparative studiesLinear time invariantsOutput feedbacksStrictly positive realVariable structure systemsLinear matrix inequalitiesTrabalho apresentado em evento10.1109/VSS.2008.4570695Acesso aberto2-s2.0-52049085801875516058014262650620873805714620000-0002-1072-3814
