This paper presents the design and implementation of a fuzzy logic controller @?LC) for a
superconducting generator (SCG) operating in a multi-machine power system. The controller is
designed and tested in a multi-machine power system which includes conventional generators. The
conventional generators are of different types and ratings. Conventional generators are equrpped
with their excitation and conventional control systems. To assess the new control strategy a fairly
detailed nonlinear model is used. A comprehensrve assessment of the proposed FLC is presented
and the simulation results are obtained in comparison with others obtained with controllers
designed based on conventional techniques. The results illustrate significant improvements in
performance when RC is used. This is obtained at different operating conditions and when the
system is subjected to a variety of disturbances and changes in system configuration.
