The design of an Hco controller for a power system stabilizer (PSS) to enhance the damping of an oscillation in Bandar- Abbas power system is presented. The unique approach used is to first treat the nonlinear characteristics of the system as model uncertainties, and then to take account such uncertainties at the controller design stage using robust control methodology. Then performance of the controller has been evaluated extensively by nonlinear simulation. It is concluded that the robust controller provides better damping to the oscillatory modes of the system than the conventional PSS in all the cases studied.
