Thread Subject: AC Brushless Motor

I'm doing a design of a ac brushless motor.

Is having problem with it, is there anyone out there can help?

(All in idea case)

1) How to form the feedback loop of it?

"present output" = "present input" + "next previous output"

I'm looking more than that.

Where should my Lq and Ld take ref from?
In a model of motor, it takes from motor.
But when replace with a motor model, I just don't know where should
Ld and Lq of the control circits should take ref from.
