A new load-dependent hysteresis model for magnetostrictive materials

Magnetostrictive materials can be used to construct high bandwidth actuators with a higher force and a larger stroke than are provided by other materials. However, their use is hindered by their complex nonlinear and hysteretic response. This response displays a significant dependence on mechanical loading. In this paper, a modeling technique is introduced for reproducing hysteresis curves at different loads. The classic Preisach model is used,...
