基于占空比调制的双三相开绕组永磁同步电机直接转矩控制

In this article, direct torque control (DTC) is first introduced into the dual three-phase open-end winding permanent magnet synchronous motor (DT-OW-PMSM). Conventional DTC based on switching table faces challenges, including large torque ripple and significant harmonic currents. To address these problems, a novel DTC based on duty ratio modulation is proposed. First, the basic voltage vectors (V...
