| Abstract: | This paper proposes a kind of synchronous generator fuzzy-PID excitation controller based on genetic algorithm(GA) and fuzzy illation.Initial factors are optimized by GA firstly.On this basis,the scale factors of PID control parameters are gained by fuzzy illation and pertinent computation based on the voltage variation and its rate of change.On line self-regulating of the PID control parameters is realized.The simulation research is carried out,and the result shows that it has excellent dynamic and static characteristics. |
