Ok finally got a chance to do some more testing. Unfortunately not a lot before my bluetooth module died.
I beat my record at the Radium test track though.
At first I was not having a good time with FOC, feeling very disconnected from the board. So I switched to BLDC mode and immediately felt way more confident with the more responsive throttle and set a great lap time. But then I switched back to FOC and started playing with these two PID settings.
I ended up with 0.006 for both Ki and Kp before the bluetooth module died but would have kept going. The board was feeling awesome and I smashed the track record by 0.6s. FOC is definitely more predictable feeling than BLDC now (however the PID controls effect BLDC as well and I’ve never tried to tune BLDC).
It definitely feels like more tuning could be done but definitely have a go playing with those two. From my reading about PID loops, probably don’t touch the Kd setting…
