Abstract

Terminal voltage of the Automatic Voltage Regulator(AVR) of brushless synchronous generator is generally being controlled by PID Control way in shore and ship field. However, in case of changeable large load on power system, PID control method is deficiency to respond output voltage with settling time. Hence, taking into consideration this situation, it is required new control method. In this thesis, we propose Fuzzy Logic Control(FLC) which has more optimal robust control way in order to respond varying values of terminal voltage to the brushless synchronous generator through simulation of MATLAB/SIMULINK and prove Fuzzy logic control more optimal compared with PID control.

선박과 육상용 브러쉬리스 동기발전기의 자동전압조정기는 출력 단자전압을 주로 PID 제어방식으로 제어한다. 하지만 발전기 전력계통에서 부하의 변화량과 변화횟수가 클 경우에는 PID 제어방식으로는 전압의 변화량과 정정시간에 대해 강인한 제어성능을 발휘하기 어려워진다. 본 논문에서는 PID 제어방식에 비해 기준 단자전압 값에 대한 추종성능이 우수한 퍼지제어방식을 사용하여 자동전압조정기의 발전기 단자전압을 조정하는 기법을 제안하였으며, MATLAB/SIMULINK 시뮬레이션을 통해 동기발전기 자동전압 조정성능에 대한 우수성을 입증하였다.
