Qualitative modelling for dynamic magnetic hysteresis

The studies of practical magnetic systems with hysteresis phenomenon are of great importance in electrical engineering. As an alternative to physical and empirical model, a qualitative model was constructed using adaptive fuzzy logic called adaptive network fuzzy inference system (ANFIS). The proposed model demonstrates the modelling and accurate capability of a hybrid system to a nonlinear dynamic hysteresis. It has been used to model the hysteresis curve versus frequency. Firstly, mathematical modeling of the dynamic hysteresis is established and then, data gathered from this model is employed to create an ANFIS model of the system. Both mathematical and ANFIS model is compared, it is shown that the proposed model can restore hysteresis cycles with a little RMS error.
