Abstract :
The approximation properties of higher order reversal hysteresis curves by means of a piecewise linear (PWL) circuit model of hysteresis are studied. The model is defined as superposition of hysteresis operators originated by suitable voltages in a simple PWL circuit. Proper identification procedures can be used to determine the parameters controlling the static hysteresis behavior, in particular for second- and higher order reversal curves. Basic features and numerical results are discussed.
