eSMO control issue

Hardy Zhou
Intellectual 1650 points

Hi

our eSMO lib uses the block diagram 3 for current observer design and back EMF calculation.

but I think the block diagram 1 and block diagram 2 is more a simple and reasonable for current observer design and back EMF calculation,

and some paper for SMO in sensorless motor control design releases with block diagram 1.

pls help clarify me, thanks
