结合模糊控制和PID算法的优点，提出并设计了模糊PID控制器，利用MATLAB软件对采用此模糊PID控制器的水轮机调节系统进行仿真研究。仿真研究结果表明，合适的隶属度对模糊PID控制系统无论是在系统响应速度,还是稳定性上都有明显的提高。

The traditional PID control is hard to use in the great nonlinearity, lag and parameter variety of a hydro-turbine generating system. The fuzzy-control has the advantages of better dynamic response characteristic, better adaptability, faster rise time and better robust characteristic, but it causes error easily because of the limitation by fussy-control grade. This paper, through a combination of fuzzy control and PID algorithm advantages, proposes a design of fuzzy PID controller to make use of MATLAB software for hydro-turbine generating system simulation. The results show that, a suitable membership to the fuzzy PID control system, whether to run at the response speed of the system or the stability, has a distinct improvement.
