... for practical engineering application. Design/methodology/approach – The model is derived using the measured and simulated data. The model coefficients are obtained in the least squares sense. Findings – Mathematical modeling of THD_I is the least expensive and the most...

... function like equation with four coefficients to fit flux linkage characteristics. In this work, the coefficients are calculated from flux‐current‐angle data using numerical curve fitting with the least squares method. A rotor position model is then derived by inverting the flux linkage model...

... of generalised radial basis function neural networks. The choice of the size of the network and the evaluation of its weights are handled by the orthogonal least squares learning algorithm. The merits of the proposed method are illustrated in the light of two examples concerning non‐destructive testing...
