Abstract
In this study, we introduce an iteration method for obtaining the distribution function of the Preisach polarization–electric field (P–E) hysteresis model for piezoelectric actuators. In a previously proposed method, numerous experimental hysteresis curves were indispensable for this function. On the other hand, by using the iteration method, only one major-loop experiment is sufficient. From this distribution function, any minor-loop hysteresis can be simulated by the Preisach distribution function F(i,j) with high resolution. First, we measured a hysteresis property of the polarization P versus input voltage V of the ferroelectric material. On the basis of this one hysteresis curve, the distribution function was obtained using the iteration method. Using this function, we could simulate the minor loops, and the simulation results showed good agreement with experimental data.
