Black Box Identification of the Phase Bulk Inductance of Current and Flux Fed Short Pitched Winding Switched Reluctance Motors

A New solution to the identification problem of current and flux fed Short Pitched Winding Switched Reluctance Motors (SPW-SRM) in the presence of strong saturation is developed. This is done by expanding the rotational periodicity and magnetic saturation in a high dimensional feature space spanned by a user defined combined periodic and smooth functions. The importance of this identification scheme lies in the good generalization ability of the constructed models, their robustness with respect to output measurement noise, and the diversity of their use as an estimation, prediction or diagnosis tool. Furthermore, no particular attention is required while the identification experiment since that data can be collected in vehicle normal operating regimes. Identification results obtained for a 60 kW SRM in the presence of measurement noise within automotive applications involving Fourier series and rational polynomial functions are quite satisfactory.
