Table 3 Fault simulation methods.
Fault type | Simulation Method |
|---|---|
Offset faults | Random numbers within the range of [0, 10] were added to the data between sample numbers 400 and 799 by means of superimposition |
High noise faults | The dataset consisting of sample numbers 800 to 1199 is created by adding random numbers from the range of [10, 20] |
Outlier faults | A random number generator was used to replace 10% of the data in the sample range of 1200 to 1599 with values in the interval of [0, 40] |
Fixed faults | The data collected is kept constant at the value measured immediately prior to the occurrence of the fault |
