A power system application of a robust decentralized controller design methodology

The paper deals with the frequency domain design of a robust power system stabilizer (PSS) foe a multivariable power system. The proposed PSS design procedure is based on a novel approach that applies the independent design methodology along with the well-known small gain theory and the robust stability conditions in the M-D setup to the so-called equivalent subsystems. Theoretical results have been applied to the design of a robust multivariable PSS for a part of the Power System of the Slovak Republic.
