我想问一下EST_getSpeed_krpm(EST_Handle handle);和EST_getFm_pu(obj->estHandle);两个函数的输出有什么区别，在实验lab05b中，一个是速度的反馈值，一个是速度PI控制器的反馈值，这两个不应该相等吗？为什么是差一个倍数关系？
Green Deng：
前者是“Gets the speed value in kilo-rpm”，后者是“Get the mechanical speed in pu/s”
kilo-rpm和pu/s通过“ST_SPEED_PU_PER_KRPM”确定比例：
4.7.1.6 ST_SPEED_PU_PER_KRPM This identifies the scaling between kilo-rpm and pu/s speed. This is used to convert from user variables which are typically in kilo-rpm into scaled speed variables. This ensures that all calculations in InstaSPINMOTION will not cause an overflow. This value is calculated from parameters that are defined in user.h
