摘要

根据权重叠加原理，提出了改进的马德隆模型。结合信号延迟响应特性（SDRC），建立了一个动态模型及其逆模型，用于描述和补偿压电致动器（PEA）随速率变化的滞后现象。实验验证了所提方法的有效性，结果表明在多频叠加信号激励下，压电致动器的滞后非线性基本消除，归一化均方根误差为 0.64%。

Modelling and compensation of rate-dependent hysteresis in piezoelectric actuators based on a modified Madelung model

Based on the principle of weight superposition, a modified Madelung model is proposed. By combining the signal delay response characteristics (SDRC), a dynamic model and its inverse model are established to describe and compensate for the rate-dependent hysteresis phenomenon of the piezoelectric actuators (PEAs). The effectiveness of the proposed method is verified by experiments, and the results show that the hysteresis nonlinearity of the PEA is basically eliminated, with the normalized root-mean-square error of 0.64% under the excitation of multi-frequency superposition signal.
