This paper proposes a model-free predictive current control (MFPCC) for interior permanent magnet synchronous motors (IPMSMs) with a multiple current difference updating (MCDU) technique. Firstly, to improve robustness against machine parameter variations and reduce the computational burden, current difference-based prediction that only requires accumulation operation is implemented, which avoids the model-based complex calculations in traditional model predictive current control (MPCC). Secondly, a MCDU technique is conducted with the characteristic of updating the current differences associated with voltage vectors in opposite directions. Thus, the updating frequency of the current difference can be significantly increased. Finally, the effectiveness of the proposed method is verified by simulation and experimental results.

采用多种电流差更新技术的IPMSM的无模型预测电流控制

本文提出了一种采用多电流差更新(MCDU)技术的用于室内永磁同步电动机(IPMSM)的无模型预测电流控制(MFPCC)。首先,为了提高抵抗机器参数变化的鲁棒性并减轻计算负担,实现了仅需要累加运算的基于电流差的预测,从而避免了传统模型预测电流控制(MPCC)中基于模型的复杂计算。其次,进行了具有以相反方向更新与电压矢量相关联的电流差的特征的MCDU技术。因此,可以显着增加电流差的更新频率。最后,通过仿真和实验结果验证了该方法的有效性。
