Hello Everyone,
I have difficulty with motor FOC control.
Motor nominal velocity is 90RPM.
Up to 40RPM I observe clear sinewave on current clamp connected to mothor phase.
When I increase velocity when it increases one spike in current waveform.
It causes motor to shake.
Is it caused by PI control ?
Or maybe it is something else wrong?
My PI regulation is like that (I gather data by uart on PC):
Best regards,
Chris
