Abstract

Research on the hysteretic-coupling between dual piezoelectric actuators under uniaxial condition and electromechanical cross-coupling under biaxial condition of the complex piezoelectric fast steering mirror (PFSM) system remains insufficiently explored, resulting in persistent challenges to achieving high-precision modeling. In this paper, a comprehensive model of the PFSM is established based on the Hammerstein structure. An improved asymmetric Bouc–Wen model is proposed to characterize the nonlinear rate-independent hysteresis, while a biaxial coupling dynamic is derived to represent the linear rate-dependent physical behavior. Considering the isolation of each module across different frequency scales, a step-by-step parameter identification method is presented. Experimental results show that the output of the identified model exhibits excellent consistency with the hysteresis, creep, and electromechanical behaviors of the PFSM. Finally, the predicted outputs are compared with those of existing comprehensive models and evaluated against measured data under various excitation signals. The significant reduction in errors validates the effectiveness of the proposed modeling approach.
基于Hammerstein结构的压电式快速转向镜高精度建模与辨识
复杂压电式快速转向镜(PFSM)系统单轴双压电致动器滞回耦合和双轴机电交叉耦合的研究还不够深入,这给实现高精度建模带来了持续的挑战。本文基于Hammerstein结构,建立了PFSM的综合模型。提出了一种改进的非对称Bouc-Wen模型来表征非线性速率无关的滞后,并推导了双轴耦合动力学来表征线性速率相关的物理行为。考虑到各模块在不同频率尺度上的隔离性,提出了一种分步参数辨识方法。实验结果表明,所识别的模型输出与PFSM的滞回、蠕变和机电行为具有良好的一致性。最后,将预测输出与现有综合模型的输出进行了比较,并与不同激励信号下的实测数据进行了比较。误差的显著减少验证了所提出的建模方法的有效性。
