The robustness about parameter variations and external disturbances are the first property
of sliding mode control system, the second is chattering phenomenon caused by non-ideal
switching action, and it's the main inconvenient of this control theory. The aim of this paper is
to develop a decentralized fuzzy-sliding mode controller (DFSMC) with a nonlinear sliding
surface for non linear multi-machine power system. The combining fuzzy logic controller and
sliding mode controller is used to exploit the advantage and eliminate the inconvenient …
