/* GENERAL NOTES:
* 1. The above parameters are over-writing the default motor parameters. For all the available parameters check BLDC_controller_data.c
* 2. The parameters are represented in fixed point data type for a more efficient code execution
* 3. For calibrating the fixed-point parameters use the Fixed-Point Viewer tool (see <https://github.com/EmanuelFeru/FixedPointViewer>)
* 4. For more details regarding the parameters and the working principle of the controller please consult the Simulink model
* 5. A webview was created, so Matlab/Simulink installation is not needed, unless you want to regenerate the code
*
* NOTES Field weakening:
* 1. In BLDC_controller_data.c you can find the field weakening Map as a function of input target: MAP = id_fieldWeak_M1, XAXIS = r_fieldWeak_XA
* 2. The default calibration was experimentally calibrated to my particular needs
* 3. If you re-calibrate the field weakening map please take all the safety measures! The motors can spin very fast!
2019-10-22 19:45:47 +00:00
* 4. During the recalibration make sure the values in XAXIS are equally spaced for a correct Map interpolation.
