摘　　要：论文介绍了基于Preisach模型的迟滞特性建模方法。通过一系列实验数据建立了Preisach模型,研究了如何应用线性插值法和BP神经网络方法进行任意Preisach函数X(α,β)值的求解,从而计算得到相应电压序列的位移,分析比较了两种方法的预测结果。实验表明,基于Preisach模型的线性插值方法方法可以更好地预测压电陶瓷执行器的迟滞位移。This paper introduces the modehng method based on the Preisach model hysteresis characteristics. Preisach model is estabhshed through a series of experimental data was studied how to apply linear interpolation method and BP neural network method for arbitrary Preisach function X（α,β） value of solving sequence of displacement, so as to calculate the corresponding voltage anatysis compares the prediction results of two methods. Experiments show that the method of linear interpolation method based on the Preisach model can better predict the hysteresis of piezoelectric ceramic actuator displacement.
