In order to improve the regulation characteristics of small hydroelectric generation sets and adapt to the requirements of modern power grid, the fuzzy control rules are applied to design a kind of fuzzy controller which is suitable for small hydroelectric generation sets. The structure of hardware circuit based on 89C51 single-chip computer and the software implementation of this fuzzy controller are also designed. The computer simulation results show that the small hydroelectric generation sets with fuzzy PID controller has better control accuracy and dynamic quality. This fuzzy P1D controller has practical significance for engineering application.
