| 摘 要： | 提出了一种基于包含零矢量模糊逻辑的永磁同步电机(PMSM)直接转矩控制(DTC)系统的实现技术.通过分析零矢量的作用,阐述了将零矢量合理地包含在模糊控制器(FLC)中的方法,使零矢量能够充分发挥在PMSM DTC中保持电磁转矩的特点.通过与以往的包含零矢量的PMSM模糊DTC控制技术进行理论分析和仿真对比,表明本文提出的技术可以有效抑制电磁转矩脉动,取得更优越的运行性能.

| Abstract: | A new direct torque control (DTC) strategy for permanent magnet synchronous motor (PMSM) based on fuzzy logic with zero-voltage vector is proposed.By analyzing the effect of zero-voltage vector in PMSM,an efficient method is expounded,which contains zero-voltage vector in fuzzy logic controller (FLC) and utilizes the feature of zero-voltage vector sufficiently.Compared with conventional DTC based on FLC with zero-voltage vector in PMSM,the strategy is able to largely reduce the ripples of both torque and fl... |
