Waveform Prediction of Blade Tip-Timing Sensor Based on Kriging Model and Static Calibration Data

Figure 13

Comparison of the predicted curve with the experimental curve when the tip clearance is 0.15 mm: (a) Kriging model with 10 sets of sample points, (b) Kriging model with 6 sets of sample points, (c) Kriging model with 5 sets of sample points, (d) Kriging model with 3 sets of sample points, (e) polynomial fit of 10 sets of sampling points, and (f) RBF model with 6 sets of sampling points.
