摘要：

This paper investigates the effect of damping ratio zeta on the performance of H infinity Power System Stabilizer (PSS). The bilinear transformation is used together with the H infinity optimal control to design the H infinity-PSS. Various zeta levels are obtained by varying the parameter backslash P1 backslash of the bilinear transformation as guided by a certain rule-of-thumb. The effect of the variation in the zeta on Sensitivity S(s) and Input Sensitivity R(s) functions are investigated. Performance comparison is also made between the nominal and worst operating conditions. Results show an improvement in the zeta as backslash P1 backslash is increased. It is shown that backslash P1 backslash may not be set very high as this may compromise robustness.
