要約(日本語): Rate-dependent hysteresis nonlinearity for giant magnetostrictive actuators (GMA, Giant Magnetostrictive Actuators). In this paper, the Prandtl-Ishlinskii (PI) model of the giant magnetostrictive drive is established. By modifying the Play operator, a modified PI (MPI, Modified Prandtl-Ishlinskii) model that can describe the asymmetric hysteresis phenomenon is designed, and the genetic algorithm is used to identify MPI model parameters. Compared with the traditional PI model, the MPI model can better fit the asymmetric hysteresis curve. The Hammerstein model is used to represent the static nonlinear part and the linear dynamic part in Hammerstein with the MPI model and the external factor input autoregressive model (ARX), so that the model can better describe the rate correlation of GMA in the frequency range of 1~100Hz Hysteretic nonlinearity.
