Figure 9.
The image shows a bar chart illustrating relative simulation times for three current transformers labeled C0, C2, and C3. The vertical axis, labeled relative simulation time, ranges from 0 to 30, and the horizontal axis lists the transformer identifiers. Each transformer has two bars, representing results from the Jiles-Atherton model and the proposed model. C0 shows the highest simulation times for both models, followed by C2, while C3 records the lowest. Error bars extend from the tops of all bars, indicating the standard deviation for each measurement. A legend identifies the bar patterns for the two models and denotes the standard deviation indicator.Due to the structure of the control-oriented model, it is possible to significantly increase the maximum step-size of the ODE15s solver to , without suffering from numerical issues
Note(s): This further decreases the relative simulation time to values below 1, which showcases the usability of the model for real-time applications
