摘      要：This paper proposes a robust power system stabilizer(PSS)for a steam synchronous generator in Barka II power *** PSS should be capable of damping small-disturbance oscillations(inherently existing in power systems due to *** changes,lines switching...etc.)within a certain settling time for different load ***,the proposed PSS must have the conventional structure and its parameters must not be *** achieve this goal,robust control provides many *** suggested controller is tuned by the Kharitonov’s theorem and uses the standard structure employed in *** problem is cast into a nonlinear constrained optimization problem to achieve the desired settling time without violating the practical values of the controller *** of the robust PSS is evaluated by several simulations in the presence of system uncertainty due to load changes.
