Abstract
This work presents a robust H∞ output feedback control design of a Power System Stabilizer (PSS). This PSS is used to damp low-frequency oscillations in power systems over a wide range of operating conditions. The H∞ control is employed in the Single-Machine connected to an Infinite Bus (SMIB) system using two weighting functions. The proposed stabilizer offers robust stability against different external disturbances and parameter uncertainties. A comparative simulation study shows a significantly enhancement and good performance of the proposed design compared to an IEEE conventional power system stabilizer.
