| Abstract: | A new method of fault diagnosis is presented in this paper.The proposed design is based on a novel strategy,which integrates knowledge-based diagnosis technique into observer-based fault diagnosis method.The proposed general framework consists of two parts:Multiple models are used to match the faults and qualitative knowledge is used to reduce the number of models during one diagnosis.Results from a DC-motor speeds regulating system simulation are presented.It indicates that the proposed method is effective. |
