TMS320F28069M: Instaspin Motion: Current Limits and Stability

Part Number: TMS320F28069M

Greetings,

I've recently been having great success using the Instaspin Motion controller in Lab 5d.  Using this, I was able to very quickly transition from using a torque control-approach for driving my motor into using the proivded speed controller. Note that my application is a motor/propeller combination, so once I get up to speed I'm starting to pull some high currents.

My motor controls quite well *most* of the time, but I had a bit of control instability for a while.  After digging through the TI E2E forums, I managed to find several posts that helped, specifically:

- this one on adjusting my inductance to achieve higher currents stably https://e2e.ti.com/support/microcontrollers/c2000/f/902/t/337103#pi316717=1
