Abstract

The objective of this paper is to design a nonlinear excitation controller of the synchronous generator based on fuzzy logic to maintain the system voltage within permissible limits by adjusting the excitation of the synchronous generator (SG) according to variation of load. The main benefit of this paper which exists in designing and implementing a fuzzy logic controller (FLC) is the ease and flexibility of the design, so FLC was applied to design an Automatic Voltage Regulator (AVR) of a synchronous generator.

The FLC constitutes a powerful tool to improve the quality of the electric voltage delivered by the SG. Simulation was carried out using Matlab Program to get the output response of the system. Simulation results, showed that the overall system response had been improved significantly when using FLC based PID controller.
