    針對反電動勢類似正弦的準正弦波反電動勢無刷直流電動機，本文提出一種基於六個離散位置信號的自同步svpwm （電壓空間矢量法）控制方法，用以削弱電磁轉矩脈動，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，阻抗角與電流超前角的合理選擇以及連續轉子位置的估計等。
  2. In order to improve the quality of the voltage signals, this paper has adopted the scheme of three phases and six organs in signal - generator part, which can eliminate the errors caused by the assembly warp and the zero shift of organs. this paper also has analyzed the distribution and varying rules of the magnetic field in the signal - generator part, then based on the conclusion of the analysis improved the structure of signal - generator, which could completely eliminate the noise signal caused by the roughness of the face on the magnetic steel ring. the improvement not only met the requirement of this study, but established the theory foundation for the super - high precision magnetic encoder in future research

    因此，為提高原始電壓信號的質量，本文採用三相六元件的信號發生方案，通過差分處理濾除了由於裝配偏差和零點漂移帶來的信號誤差;本文對編碼器信號發生結構進行了磁場分析，依據磁場分析的結論對編碼器常用的信號發生結構進行了改進，改進后的結構利用積分原理在理論上能夠完全消除信號中由磁鋼環表面粗糙度引起的信號噪聲，進一步提高了信號質量，此結構不僅滿足了本課題的需要，而且為今後研製超高精度的磁電式編碼器奠定了理論基礎。
