Hi,

I'm new here and have been reading quite a bit already. Still need to do a lot and I definitely need to work on some of my maths as it looks like a lot if the control logic is based on some mathematical functions.

I found the next university paper on an extended back EMF algorithm but my
rusty maths and lack of knowing, what seems to be symbol conventions, make me not understand a lot of it. I will share it anyway.

If there is someone who could point me to the right reading material to educate myself on these things, I would appreciate it.

Extended Back EMF model for permanent magnet synchronous machine with different inductances in d- and q-axis:

Regards,

Geoff
