电机设计专家系统中的知识表达及应用

目前，电机设计专家系统在规则表达形式不直观的问题，影响了知识的形式化和知识库的维护。为解决这一问题，本文首先定义了一种直观、自然的规则表达形式，给出了知识库结构和完善的语法规则；在此基础上，用Ｃ语言开发了高效的推理机。最后将本文的成果应用于“永磁直流电动机设计专家系统”，应用效果良好。

Knowledge Expression and Application in Electrical Machine Design Expert System

So far, the expression form of rules in existing electrical machine design is not easyto read or use, which affects the utilization of knowledge and rnaintenance of knowledge-base. To solve this problem, a kind of expression form of rules which is easy toread and use, the structure of knowledge-base and corresponding granunar are given in thispaper. At last, the above achievements are applied to the design expert system of permanentmagnet direct current motor.
