摘要
研究了一种新型的永磁同步电机直接转矩控制方案。分析了由于空间电压矢量的非连续性导致的转矩脉动。综合利用空间电压矢量细分技术和空间电压矢量调制技术,产生新的空间电压矢量,将其应用于永磁同步电机的直接转矩控制,抑制了由于空间电压矢量非连续性导致的转矩脉动。仿真结果验证了理论分析。
This article studied a novel direct torque control (DTC) of permanent magnet synchronous (PMSM). The torque ripple due to the discontinuity of voltage space vectors was analyzed. Vector subdivi- sion and space vector modulation (SVM) were applied, and the number of voltage space vectors was in- creased. All the voltage space vectors were applied to the DTC of PMSM, and suppressed the torque ripple due to the discontinuity of voltage space vectors. Simulation result confirmed the theory analysis.
