Multi-Layer Immune Model for Fault Diagnosis

Inspired by the multi-layer defense mechanism and incorporates the feedback mechanism in the nature immune system, the paper proposes a multi-layer immune model for fault diagnosis. In the multi-layer model, inherent immune layer direct recognition of known fault that could not cause influence to other nodes; propagation immune layer adopt the structure of the B- lymphocyte network to construct the fault propagation network for the fault localization; Adaptive immune layer learn the unknown fault pattern. Simulation results show that the multilayer immune diagnosis system has the properties of recognition, learning and memory.
