Yes! Well, what I have been doing is, when there is a gross violation of the clamping (VdClamped - Vd) > 100, knock down the commanded Id by 100. As if giving it another chance, allow the "commanded" current crawl back very slowly to the ACTUAL commanded current. If there's another violation of Vd or Vq, tar whoop them again!

The process needs to be cleaned up, but that has worked best. Another way is, I think I need to find the relationship between Id, Iq and RPM and load for all possible values (for a given AC voltage). Because that wouls be difficult, I'm trying to be content with only using Vd, Vq, Id, and Iq, since I have those.
