中文摘要

本文提出了一种基于线性自抗扰控制(LADRC)的前馈电流控制策略,用于操纵变磁通记忆电机(VFMM)的磁化状态。通过设计线性扩张状态观测器(LESO),实时估计永磁体感应电压及系统扰动,有效提升了电机磁化状态调节的精度与鲁棒性。

English Abstract

In this article, a novel current control strategy is proposed to manipulate the magnetization state of the variable flux memory machine (VFMM) through a newly developed linear active-disturbance-rejection-based feedforward current controller. A linear extended state observer is designed to estimate the sum of the permanent magnet (PM) induced voltage and the disturbance voltage caused by the susce...
