AI 中文摘要
针对内置式永磁同步电机（IPMSM）无传感器控制中常见的参数敏感性问题，本文通过将自适应磁链观测器从表面式永磁同步电机扩展到凸极电机，提出了一种参数鲁棒的控制框架。首先，参数失配被解释为具有d轴和q轴分量的等效磁链矢量。永磁磁链、d轴电感和电阻失配被映射到d轴磁链分量，而q轴电感失配被映射到q轴分量。然后，设计了一种标量自适应磁链更新，通过跟踪等效磁链幅值来补偿d轴磁链变化。由于q轴分量旋转了观测磁链方向且无法通过标量自适应消除，引入了一种高频q轴电压注入方法来识别q轴电感。同时，稳定性分析证明了等效磁链幅值跟踪的有界性，并识别了导致位置误差的残余切向磁链。最后，实验结果表明，所提出的方法不需要精确的电阻、d轴电感或磁链，而q轴电感通过在线辨识提供。
英文摘要
To address parameter sensitivity commonly in interior permanent magnet synchronous motor (IPMSM) sensorless control, this paper proposes a parameter-robust control framework by extending the adaptive flux observer from surface-mounted PMSM to salient-pole machines. First, parameter mismatches are interpreted as an equivalent flux vector with $d$-axis and $q$-axis components. Permanent magnet flux, $d$-axis inductance, and resistance mismatches are mapped to the $d$-axis flux component, whereas $q$-axis inductance mismatch is mapped to the $q$-axis component. Then, a scalar adaptive flux update is designed to compensate the $d$-axis flux variation by tracking the equivalent flux magnitude. Since the $q$-axis component rotates the observed flux direction and cannot be eliminated by scalar adaptation, a high-frequency $q$-axis voltage injection method is introduced to identify the $q$-axis inductance. Meanwhile, stability analysis proves bounded equivalent flux magnitude tracking and identifies the residual tangential flux responsible for position error. Finally, experimental results show that the proposed method does not require precise resistance, $d$-axis inductance, or flux, while the $q$-axis inductance is provided by online identification.
