摘要: |
针对故障诊断专家系统中专家知识的模糊性和不确定性,给出用模糊Petri网(FPN) 模型表示模糊产生式规则(FPR)知识的方法、知识的存储、模糊推理机制及算法的实现。同时以JCS-020 (FANUC) 加工中心主轴伺服故障诊断为例,说明该方法在故障诊断专家系统 (FDES) 中应用的可行性与有效性。 |

Abstract: |
In view of the Fuzziness and the uncertainty of the expert knowledge of the fault diagnosis expert system,this paper presents a method of Fuzzy production rule (FPR)knowledge representation by using Fuzzy Petri nets(FPN)model,knowledge store and Fuzzy reasoning mechanism,and gives the algorithm implementation. Furthermore,taking the fault diagnosis expert system for the JCS-020 (FANUC) manufacturing center as an example,We have proved in this paper the feasibility and validity of the method. |
