An adaptive fuzzy inference system for 3-phase synchronous generator excitation control

Abstract EN

This paper proposes the excitation system control of three phase synchronous generator for improving the step response using an adaptive fuzzy controller.

The dynamic model and simulation of 3-phase synchronous generator are proposed.

The open loop voltage control responses under no-load and full-load conditions are proposed too.

The PI closed loop controller of excitation system is illustrated as a conventional control method, which gives an acceptable operation behavior of synchronous generator terminal voltage.

An adaptive fuzzy inference system is proposed in this paper as a close loop controller, which gives an ideal performance in both of no-load and full-load conditions as compared with PI controller to control the 3-phase synchronous generator excitation system.

Simulation results show the effectiveness of the proposed fuzzy controller scheme which gives in fuzzy controller; rise time = 0.3 sec., overshot = 0%, settling time = 0.3 sec., and steady state error = 0%.

Whereas, in PI controller; rise time = 0.55 sec., overshot = 20%, settling time = 2.8 sec., and steady state error = 0%.
