永磁同步电机弱磁区电流耦合控制分析与优化

Different from the independent control of dq-axis current (i$_{{ sd,q}}$) in the base-speed region, the flux-weakening (FW) region requires coupling control of i$_{{ sd,q}}$ to satisfy the maximum voltage constraint. This article revealed the reasons for the failure of the rapid current coupling control in FW region from the perspectives of control structure and vector trajectory. The direct and i...
