为了成功地充分发挥压电致动器在微/纳米定位系统中的全部潜力，必须对其磁滞行为进行精确建模。本文提出了一种新颖的压电执行器磁滞模型。首先，提出了段相似性，描述具有不同转折点的滞回曲线段之间的相似关系。时标相似性描述了不同速率的滞回曲线之间的相似关系，用于解决动态效应问题。所提出的模型是利用这些相似性来制定的。最后，针对微纳米运动平台系统进行了实验。与Preisach模型相比，验证了所提模型的有效性。实验结果表明，该模型能够精确预测压电执行器的磁滞轨迹，并且性能优于Preisach模型。
To successfully exploit the full potential of piezoelectric actuators in micro/nano positioning systems, it is essential to model their hysteresis behavior accurately. A novel hysteresis model for piezoelectric actuator is proposed in this paper. Firstly, segment-similarity, which describes the similarity relationship between hysteresis curve segments with different turning points, is proposed. Time-scale similarity, which describes the similarity relationship between hysteresis curves with different rates, is used to solve the problem of dynamic effect. The proposed model is formulated using these similarities. Finally, the experiments are performed with respect to a micro/nano-meter movement platform system. The effectiveness of the proposed model is verified as compared with the Preisach model. The experimental results show that the proposed model is able to precisely predict the hysteresis trajectories of piezoelectric actuators and performs better than the Preisach model.
