模糊控制器的设计不依靠被控对象的模型，而是依靠控制专家或操作者的经验知识。模糊控制的突出优点是能够比较容易地将人的控制经验溶入到控制器中，但若缺乏一定的控制经验，很难设计出高水平的模糊控制器。而且，由于模糊控制器采用了IF-THRN控制规则，不便于控制参数的学习和调整，使得构造具有自适应的模糊控制器较困难(The design of fuzzy controller does not depend on the model of the controlled object, but depends on the experience of the expert or operator. The prominent advantage of fuzzy control is that it is easy to integrate human control experience into the controller, but it is difficult to design a high level fuzzy controller without a certain control experience. Moreover, because the fuzzy controller adopts the IF-THRN control rule, it is difficult to study and adjust the control parameters, so it is difficult to construct an adaptive fuzzy controller)
