  1. For the bldcm which has a pseudo - sinusoidal back - emf waveform, this dissertation presents a svpwm control method using six discrete position signals for minimizing the torque ripple. the main aspects for the implementation of this method are analyzed, including the initial orientation of the voltage vector, reasonable choice of the impedance angle and the advance commutation angle, and estimation of the successive rotor positions

    針對反電動勢類似正弦的正弦波反電動勢無刷直流電動機,本文提出一種於六個離散位置信號的同步svpwm (電壓空間矢量法)控制方法,用以削弱電磁矩脈動,分析了實現這種方法的主要控制環節,包括起動時電壓空間矢量的初始定位,阻抗與電流超前的合理選擇以及連續子位置的估計等。
  2. Furthermore, this dissertation also gives a comprehensive analysis and comparison to the torque ripple factor, torque - current ratio and other aspects for pseudo - sinusoidal emf bldcm drived by 120 conduction mode, 180 conduction mode and self - synchronous svpwm mode respectively. the simulation and the experimental results indicate that self - synchronous svpwm method is more effective for minimizing the torque ripple without any expense of the torque - current ratio when the crest width of the back - emf waveform is less than 107 electrical angles

    正弦波反電動勢無刷直流電動機在120導通方式、 180導通方式和同步svpwm三種控制方式下的矩脈動系數、矩電流比等方面進行了全面的分析與比較,模擬研究和實驗結果表明,當反電動勢的平頂寬度小於107電時,採用同步svpwm控制方法可以在不損失矩電流比的礎上,更有效地抑制電磁矩脈動。
