Inverse Problem Solution and Regularization Parameter Selection for Current Distribution Reconstruction in Switching Arcs by Inverting Magnetic Fields

Figure 6

Simulation II. Mean values of relative error on currents (a) and on magnetic fields (b) versus noise ratio with four parameter selection criteria. The mean values are computed in 100 repeated runs for each value of noise ratio with the noise generator randomly producing Gaussian noise.
