正弦的 meaning in Chinese
sinusoidal
Examples
- Most of the traditional real - time detecting method for harmonic current is based on sinusoidal voltage or locking the voltage phase accurately , which deviating from the real circumstances
由于传统的谐波电流实时检测方法大都是基于正弦的电压系统或对于电压波形达到精确锁相的前提，而现实情况却往往不是如此。 - 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。
