【摘要】 直接转矩控制是继矢量控制后发展起来的一种新型高性能调速技术,然而在传统的直接转矩控制中,转矩和磁链会有较大的脉动。通过对转矩和磁链脉动的研究,提出将磁链扇区由传统六扇区划分为十八扇区,此外结合零矢量和定子电阻补偿,通过仿真分析可以看出,该方案可以有效地减小磁链和转矩脉动,并且提高了系统对电机参数变化的鲁棒性。更多还原

【Abstract】 Direct torque control is a new high-performance control technology,appeared after vector control.However traditional direct torque control has a greater torque and flux ripple.According to the research of torque and flux ripple,a new eighteen-sector control strategy combines with zero-vector and stator resistance compensation was presented.The analysis of simulation shows that the program can reduce flux and torque ripple and improve the system parameters of robustness.更多还原
