Low order transfer function identification and robust PSS control design

This paper presents a low order identification technique suitable for power system damping controller design, which is based on standard Prony analysis. The proposed identification technique when combined with a robust controller design can be used to tune power system stabilizers (PSSs) for a number of operating conditions. Technical background of the method is presented first, and then a benchmark power system model is used to illustrate the proposed identification and controller design techniques.
