The shortcoming of using voltage and power to describe the voltage critical state is analyzed and the load impedance angle is introduced for the critical point of voltage . the ternary analysis method of voltage v , power p and load impedance angle is established
本文首先分析了采用电压和功率描述电压临界状态的不足,提出了引入负荷阻抗角的三个参数来描述电压临界状态,即电压v 、功率p和负荷阻抗角的三元分析法。
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
针对反电动势类似正弦的准正弦波反电动势无刷直流电动机，本文提出一种基于六个离散位置信号的自同步svpwm (电压空间矢量法)控制方法，用以削弱电磁转矩脉动，分析了实现这种方法的主要控制环节，包括起动时电压空间矢量的初始定位，阻抗角与电流超前角的合理选择以及连续转子位置的估计等。
