Hi everyone,
I tried to simulink the sensorless FOC observer Ben used in his code. I used fixed observer gain and I changed this value in a wide range (from 1000 to 50000), but the observer could only track the position in low speed and failed in high speed. In Ben's code, I saw him changed this value every observer update.
Is this the key for high speed tracking?
Thanks a lot.
