Table 6
Comparison of the proposed fault diagnosis method and other fault methods.
| Fault diagnosis method | Objector | Diagnosis time | Robustness | Cost | Fault type |
| The neural network method | Both | More than one cycle | Low | Low | Single | The fuzzy logic method | Both | More than one cycle | Medium | High | Multiple | Park’s vector approach | Open-loop | More than one cycle | Low | Low | Single | Spectrum analysis method | Both | More than one cycle | Medium | High | Single | The proposed method | Both | About 1/3 cycle | High | Low | Multiple |
