Decided to make another release.

I have added the throtmin parameter so that regen can be limited temporarily from outside. I use this for antilock braking and charge power limiting.
There are some improvements and cleanup in FOC code:
- I have removed the bus voltage limiting field weakening controller, so now there is only one fwkp parameter left
- I made curki frequency dependent by the curkifrqgain parameter.

So integral gain increases with speed. This ensures good regulation in upper rev range while not being jumpy at low speeds.

Compiled code .bin and .hex for the uninitiated please.

Oh, wrong link, corrected
Erm, could you do more precise quoting in general Like only the relevant line

Check!

Great

Hello Johannes,
Thanks for the update.
I've searched the code and documentation to understand how the parameters drive the Regen Algorythm, but could find out how it works.
Could you point me out to the documentation, if any, or to the portion of code that handles Regen ?
thanks !

There is no such thing as "regen" code. It is naturally part of the control algorithm, just with negative slip (sine variant) or negative iq (FOC variant). In throttle.cpp you'll find how regen is controlled via throttle pedal and brake pedal.

Ok, I see. I'll read again.
thanks !
