Research of Hysteresis Motor Based on Prandtl-Ishlinskii Model

Prandtl-Ishlinskii模型作为目前常用的动态迟滞拟合模型较广泛地应用于压电陶瓷控制中,但在磁滞电机控制中鲜有应用。本文旨在使用实验方法探究证明Prandtl-Ishlinskii模型在拟合磁滞回线中应用的可行性,并使用该模型对理想化的径向磁通的磁滞电机磁路进行分析。结果发现与其他常用模型相比,Prandtl-Ishlinskii模型更适用于磁滞电动机特性的研究。

Prandtl-Ishlinskii model was considered as a popular dynamic hysteresis model in the field of piezoelectric actuator but merely in the field of hysteresis motor.In this study,we tried to prove the possibility of applications of Prandtl-Ishlinskii model in the field of simulate hysteresis loops,and analyzed the the magnetic circuit of hysteresis motor in the use of Prandtl-Ishlinskii model.We found that compared with other model,Prandtl-Ishlinskii model is more suitable to the research of hysteresis motor simulation.
