Hello, Ti engineer
I am using the PMSM: FOC Sensorless (Delfino F2833x) program from controlSUITE's High Voltage Motor Control and PFC development kit. I'm testing level3. When I read the document, I saw this passage

But I can't find pi_id.Fdb in the struct definition. Then I see TI's DMC_MATH.pdf

I don't know if pi_id.Fdb and pi_id.Fbk mean the same thing. If it has the same meaning, should we observe pi_id.Out ? Should we trace pi_id.Out of the PI module instead of pi_id.Fbk (piid.fdb)?
