本文首先介绍了三种专门用于模糊逻辑控制系统设计的软件系统。详细地介绍了利用软件进行模糊逻辑控制系统设计的基本原理以及模糊控制器的软件程序设计方法。实验表明，模糊逻辑系统的C 语言实现方法是完全可行的，并且能够大大减少工作量。关键词：模糊逻辑 C 语言Abstract: This paper presents three special software systems for the the design of hardwarecircuit of Fuzzy Logic control system. The paper introduced the composing and workingprinciple in detail . The way of designing and programming of Fuzzy Logic control system is also presented in detail in the paper. In the end the results of experiment shows that C Language realize method is completely viable,and can reduce lots of workload.Key words: Fuzzy Control C Language
