This paper presents a new adaptive power system stabiliser able to provide acceptable damping over a wide range of operating points. The control strategy is based on a new adaptive technique named Pole-Zero Assignment Controller in which a particular power system transferfunction (Gd(s) = ∆δ/ ∆Pm) is modified to a standard form based on an explicit system identification. Controller design is mainly based on continuous-time system because of using the delta operator rather than the more usual shift operator. Simulation studies performed on a single-machine-infinte-bus model are presented. Results clearly show the benefits of the proposed adaptive controller for stability enhancement of apower system.
