A method of improving the performance of discrete fuzzy logic control (FLC) when applied to different systems will be proposed in this paper. Improvements to the controller performance have been made in terms of steady state error, lowered ripple heights, and decreased settling time, particularly with respect to a multi-machine power system. Regarding our methodology, a truth-table was first pre-calculated, allowing direct mapping of given inputs to a suitable output following basic fuzzy logic operations. Next, a novel method of increasing the resolution of the FLC when the output nears the reference signal was implemented. Finally, simulations were run to prove the effectiveness of the proposed method compared to conventional control schemes in both linear and non-linear systems.
