基于虚拟电流约束的表贴式永磁同步电机弱磁运行分段轨迹控制策略

This article proposes a virtual current constraint based segmented trajectory control strategy for surface-mounted permanent-magnet synchronous motor drives, to improve the transient performance under the flux-weakening operation. In the conventional scheme, the operating points (OPs) are arranged on the current constraint circle during the speed-rising process to provide the maximum electromagnet...
