摘要
把磁通轨迹法应用到直接转矩控制中,在保持系统良好性能的前提下,用等12边形逼近圆形磁通轨迹,使控制过程简化。实践证明,在控制单元运算速度不太高的情况下,这是一种缩短转矩控制周期的有效方法。
This paper treats of the application of flux track control to the direct torque control system.The approach methods of flux track are analyzed,the applied position and time of torque calculation as well as zero voltage vector are determined.Twelve flux vectors are used to approach round flux track in the case of keeping good performance.Thus,the control processes are simplified.It is proved that this is an efficient method to shorten the control cycle when the calculation speed of the control unit is not so high.
