Abstract: Wide range of electrical apparatus used in industrial application require automatic voltage regulator for stability purpose. As the loud on an alternator is varied, its terminal voltage is also found to vary. This variation terminal voltage is due to voltage drop in armature and armature reaction, therefore this paper aims to design voltage regulator to maintain the terminal voltage of alternator at constant value at load condition. The armature voltage of a synchronous generator is controlled by varying the field voltage using fuzzy logic based control method. Voltage difference between the immediate output voltage and the rated voltage of the generator is used to process the rate of change of voltage error. The amount of armature voltage that has to be applied to the alternator is varied by the controller to keep the output of alternator at its rated value. The system is designed and simulated using MATLAB simulink.
