摘要
介绍了专家系统的基本原理、知识获取和表示的基本概念 ,讨论了现在应用最为广泛的规则表示法 .结合水轮发电机组故障诊断实例 ,对专家知识库的设计策略、实施步骤和组织结构进行了详细论述 ,并就目前应用于故障诊断领域的神经网络技术进行了探讨 .
Knowledge acquisition and expression are the basic and core contents of Fault Diagnostic Expert System (FDES).This paper described the basic principle of FDES,the elementary concepts of knowledge acquisition and expression,and studied the most wildly used rule based expression method.Based on the examples,the paper dealt the design,the steps and the structures of the Knowledge Base with details,and then the Neural Network Based Fault Diagnostic Expert System in the field is described for a deeper study.
