A possible solution to this could be just basic speed ramping. |
Also, what happens if you go from full forwards to full reverse? Theoretically, you get 2x stall current. Practically speaking, you'll start saturating magnetic fields at some point, so it gets hard to model. Stall is a good starting point.
