Power System Stabilizer (PSS)

P(s,a) = dynamics of generator(s) linearized about an operating point, with a ? ?a parametric uncertainty

Problems:

• Robust Analysis: Given a controller, GPSS, is the closed-loop system stable for all a ? ?a ?

• Robust Design: Find a controller such that closed-loop system is stable for all a ? ?a.

PSS: provides rotor angle stability
