Abstract

The control accuracy of PMSM depends largely on the inductance. In the traditional inductance identification methods, the ideal PMSM mathematical model is applied, where d-axis and q-axis are assumed completely decoupled. In this case, only the d-axis and q-axis inductances are considered. However, the cross-coupling effect exists in the actual model of PMSM, which leads to the mutual inductance between d-axis and q-axis. In this paper, a high-frequency (HF) equivalent impedance model of PMSM under virtual axis is proposed. According to the HF signal injection, the inductance matrix of PMSM considering the cross-coupling effect can be accurately identified. The experimental results show the effectiveness of the proposed method under different PMSM operation conditions.
