针对永磁同步电机的传统直接转矩控制中的磁链和转矩脉动大的缺点,提出了十二扇区细分的磁链闭环控制方法和相应的电压开表。分析了电压矢量对电磁转矩和定子磁链的作用,得到有限的扇区和电压矢量会造成转矩和磁链脉动大。理论和实验对比分析了六扇区划分和十二扇区划分的控制性能。实验结果表明十二扇区划分的PMSM直接转矩控制方法,既保证了DTC的快速性,又很好地降低了转矩与磁链脉动。
-For the tradition of permanent magnet synchronous motor direct torque control flux and torque ripple big disadvantage, raised twelve sectors subdivision flux loop control method and the corresponding voltage to open the table. Analysis of the voltage vector of the electromagnetic torque and stator flux role, received limited sector and the voltage vector can cause large torque and flux ripple. Theoretical and experimental comparative analysis of six and twelve sectors divided into the control performance of the sector. Experimental results show that the twelve sectors divided PMSM direct torque control method, both to ensure the DTC fast, and very well reduce the torque and flux ripple.
