Abstract :
We present a new identification procedure for a hysteresis model based on nonlinear circuit cells. The response of elementary cells is equal to a generalized play operator. The procedure identifies exactly the limit symmetric hysteresis loop and can minimize the reconstruction error on minor loops. We present test cases for three different soft magnetic materials with peculiar behavior and we discuss the results.
