众所周知，欧拉角和四元数是存在对应关系的。后者用于导航等时不存在死区现象，而且，精度高，计算简单。(known, the Euler angles and quaternion is a correlation between them. Navigation for the latter did not exist at the Dead phenomenon, and with high accuracy, is simple.)

逆变器的调制方法有多种，如单极性调制，双极性调制，单极倍频调制等，此处是单极性调制，并给出单极性调制发生器(There are many modulation methods for inverters, such as unipolar modulation, bipolar modulation, unipolar frequency modulation, etc. This is unipolar modulation, and a unipolar modulation generator is given)
