不平衡永磁同步电机低转矩与磁链脉动的级联直接转矩控制

During operation or manufacturing, the electrical machines are often exposed to parasitic impedance in the phases, causing unbalanced three-phase currents and increased torque and flux ripples. To mitigate the undesired torque and flux ripples, this paper presents a modified cascaded direct torque control strategy for three-phase PMSMs, having asymmetric phase impedances. The proposed method aims ...
