Fault Diagnosis for Hydraulic Servo System Using Compressed Random Subspace Based ReliefF
| Fault mode | Fault phenomenon | Fault injection mode |
| Normal state | - | - | Electronic amplifier fault | Magnification notably increases | Multiplying the gain by 0.25 | Sensor fault | Constant gain | Setting the feedback of the sensor to 0.5 | Hydraulic wear fault | Output flow decreases | Setting flow-pressure coefficient of the variable orifice valve to 0.03 |
