摘要
在一种改进的直接转矩控制方法基础上,采用三点式磁链调节器,改变开关控制策略,减小异步电动机的转矩脉动,得出了平滑的圆形磁链轨迹曲线,以及转速和转矩曲线,仿真结果证明所设计的系统具有优越的转矩静、动态性能。
On the basis of a new improved control method,three point flux regulator is used,and the switch control rule is also changed to reduce torque pulsation.In this paper,the smooth and approximate circle flux trajectory,the speed curve as well as the torque curve are presented.The system is verified to be of good static and instantaneous torque performance through simulation.
