A Fault Diagnosis Method for Rotating Machinery Based on PCA and Morlet Kernel SVM
Table 2
The states recognition rate of three different methods (recognition rate
%).
| States recognition methods | Normal state | 0.18 mm fault depth | 0.36 mm fault depth | 0.53 mm fault depth | 0.71 mm fault depth |
| Without PCA dimension reduction | 91 | 61 | 76 | 83 | 81 | Use the LTSA method dimension reduction | 90 | 83 | 90 | 84 | 88 | Use the LPP method dimension reduction | 96 | 92 | 98 | 98 | 100 | Use the PCA method dimension reduction | 100 | 100 | 100 | 100 | 100 |
