Parameter identification of a modified dynamical hysteresis model with immune clone algorithm
This paper focuses on application of immune clone algorithm to identify parameters of a modified dynamical hysteresis model for giant magnetostrictive materials (GMM).The domain flexing function proposed by Damijan Miljavec et al,is added into this model,which resulted in one extra parameter,to overcome the unphysical negative susceptibility problem.Thus,the immune clone algorithm is applied to identify the parameters in this revised model.The efficiency of the parameter identification with immune clone algorithm is verified by comparing the model generated curves between the identified parameters and the selected parameters.Moreover,it can be seen the unphysical behavior of minor hysteresis loop is suppressed by comparing the identified model curve with the original model curve and a set of representative experimental data.
