Design of a non-linear power system stabiliser using the concept of the feedback linearisation based on the back-stepping technique

摘要

This study proposes a feedback linearisation based on the back-steppingmethod with simple implementation and unique design process to design anon-linear controller with a goal of improving both steady-state and transientstability. The proposed method is designed based on a standard third-ordermodel of synchronous generator. A comparison based on simulation is thenperformed between the proposed method and two conventional control schemes(i.e. conventional power system stabiliser and direct feedback linearisation).The simulation results demonstrate that fast response, robustness, damping,steady-state and transient stability as well as voltage regulation are allachieved satisfactorily.
