TMS320F280039C: InstaSPIN estimation config params

These 3 parameters are used in the following 3 functions that are a new patch for the low-inductance, low voltage and high current motor. There are not a detailed description about these functions in the lab/user’s guide, but there is a comment about the settings of these parameters in the user_mtr1.h file. If the motor is a typical PMSM, the user can use the default values in the header file or don’t need to call these 3 functions.

    // set the scale factor for high frequency motor

    EST_setOneOverFluxGain_sf(obj->estHandle,

                              obj->userParamsHandle, USER_M1_EST_FLUX_HF_SF);

    EST_setFreqLFP_sf(obj->estHandle,

                      obj->userParamsHandle, USER_M1_EST_FREQ_HF_SF);

    EST_setBemf_sf(obj->estHandle,

                   obj->userParamsHandle, USER_M1_EST_BEMF_HF_SF);
