Frequency response characteristics of the fuzzy polar power system stabilizer

A fuzzy polar power system stabilizer (FPPSS) which was recently developed is analyzed using frequency domain methods. The frequency domain approach allows the PSS designer to compare the new FPPSS with more conventional controllers. The significance of the three FPPSS design parameters are readily seen from the frequency response data, and their relationship to the conventional lead-lag design approach can be evaluated. Furthermore, the frequency response data for the FPPSS allows an alternate design approach for this stabilizer, and can be used to develop information concerning the small signal stability of the resulting power system.<
