Hi,
For a testing purpose, I am looking for way to break in the FOC blocks somewhere, to generate driving motor driving waveform in open loop fashion, without using any of the current and voltage feedback.
I wonder if using seeded values into SVM module is feasible? Something like below:
1) LUT/Calculated values of Va, Vb values that get fed into SVM module
2) LUT/Calculated values of Vq, Vd, and angle that get feed into IPARK
Seeded values are to be able to be multiplied by a scalar value to control the final winding current.
I understand that when pair with motor of different Ls and Rs, this will generate different level of winding current. Another goal for this control is to remove the range limitation of current sensing and feedback circuit when performing the test.
Can anyone help the the LUT or fomulas that can generate required seed values for Vq/Vd/angle or Va/Vb?
