چکیده مقاله :
The power system stabilizer (PSS) is capable of improving network stability by damping oscillations. PSSs generate control signals for exciting system which are used to damp volatility resulting from impairment of the power system. To overcome the shortcomings of the conventional power system stabi lizers by the use of feedback linearization control (FBLC) and H-infinity (H¥) robust optimal control, two synchro no us generator excit i ng system controllers were designed. The main objective is to design these controls to adjust the voltage and improve the stability of the power system small signal simultaneously despite uncertainty and disruptions to enter the power system. The simulation results obtained by MATLAB in a single machine to infinite bus (SMIB) system show that control proper functioning in different operational conditions, and are designed to be an appropriate alternative to conventional with automatic voltage regulator (AVR).
