摘要
传统preisach模型具有次环一致特性,压电陶瓷执行器迟滞特性不满足其特性。采用传统preisach模型建模精度较低,因此,该文提出一种改进型preisach模型,推导出离散化计算方法,其数值实现采用三线性插值法。在PI公司生产的E-625系列压电陶瓷控制器平台上针对此算法进行相关实验设计和结果的验证。实验结果表明,该文提出的基于三线性插值法的preisach模型其绝对误差最大值为0.2μm,提高了压电陶瓷preisach模型精度。
The traditional preisach model has the characteristics of the secondary loop consistency,and the hysteresis characteristics of the piezoelectric ceramic actuator do not satisfy its characteristics.The traditional Preisach model has low modeling accuracy,so an improved Preisach model is proposed in this paper.The discretization method is derived and its numerical implementation is based on the trilinear interpolation.The verification of the experimental design and results of this algorithm are carried out on the E-625 series piezoelectric ceramic controller platform fabricated by PI Company.The experimental results show that the preisach model based on trilinear interpolation method proposed in this paper has a maximum absolute error of 0.2μm,which improves the precision of the piezoelectric ceramic preisach model.
