Application Research for Fault Diagnosis of Machine Unit Based on Immunology Principle

In this paper, non-dimensional parameter immune detectors are constructed using some non-dimensional parameter which are more hypersensitive to single fault combined with negative selection mechanism of artificial immune system. Regarding complex fault as a type new occurring fault and is gone into fault space to train, fault character can be extracted, and fault can be diagnosed. The machine unit experiment results show that the proposed method is effective.
