基于自适应电压参考渐进回退的永磁同步电机弱磁运行平滑过渡策略

When operating a permanent magnet synchronous motor (PMSM) from the base speed region to the field-weakening region in an extremely short time, the excessive voltage overshoot often leads to slim voltage margin, which deteriorates the current control and poses a risk of losing controllability. To mitigate this issue, a smooth transition strategy is proposed to improve the dynamics of the voltage-r...
