A new H∞ based PSS design using numerator–denominator perturbation representation

Abstract A new H∞ PSS design method which uses the numerator–denominator perturbation representation and includes the partial pole placement technique and a new weighting function selection method is proposed. This overcomes certain conventional H∞ PSS design algorithm limitations. A robust PSS has been successfully designed by treating the highly non-linear characteristic of the power system as model ‘uncertainty’. The design is verified to have better performance for a wide range of system operating conditions when compared with the conventional PSS design.
