适合用来学习模糊控制的源码。模糊自适应PID效果是非常不错。PID控制器，一种工业控制方式,比例积分微分控制规律（控制器数学模型G(S)=比例＋微分＋积分）,经常用P表示比例，用I表示积分，用D表示微分。(Suitable for learning fuzzy control of the source. Fuzzy adaptive PID effect is very good. PID controller, an industrial control, PID control law (mathematical model of the controller G (S) = ratio of+ differential+ points), often expressed by P ratio, with the points I said, with the D that differential.)

里面是一些大家很可能常用到的聚类分析方法有像K均值等分析法，希望能为大家提供一些帮助。(There is probably some people used to the cluster analysis methods such as K-means analysis, We hope to provide some help.)
