无传感器永磁同步电机仿真，基于滑膜变结构控制(Sensorless permanent magnet synchronous motor simulation, based on variable structure sliding mode control)

说明：  SAR成像的算法很多，以上文件为简单易懂的条带SAE成像RD算法。忽略距离徙动和距离弯曲的影响。(Many SAR imaging algorithm , the above file with SAE imaging RD algorithm is simple and easy to understand article . Ignore the range migration and distance bending . )

说明：  生成复杂网络之BA无尺度网络，有详尽的原理描述和参数说明。(BA generate complex networks of scale-free networks, there is a detailed description of the principles and parameters.)

数据整理，数据和标签和样本数量之间的匹配，当然也可以用其他方法，仅供参考(Data collation, matching between data and label and sample quantity, of course, other methods can be used, for reference only)

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.)
