Re: state of the project

[<de...@jo...>]

Hi everyone,

thanks for the reference, Philip.
So even though I sort of took off with my own hardware, I still consider
the software as part of the tumanako project and the code is also still
hosted in the tumanako git.

As you might know I am happily driving around in my tumanako powered car
and so are about 30 more people (although most of them still seem to be
"driving" on their workbench only).

So here is what I have:
- Working motor/vehicle control firmware
It uses pure slip frequency/amplitude control and achieves high motor
efficiency and power. My Polo uses 12kWh/100km off the wall and the
entire system is passively cooled. I have come to the conclusion that
FOC offers no advantage if a speed sensor is being used. Theres also
things like variable regen, cruise control etc.
- A web interface for configuration and monitoring
- A bootloader for upgrading the firmware over USART3 which does not
interfere with the timer outputs and only needs RX/TX wires.
- We are currently experimenting with synchronous motor (some Lexus
drivetrain) and it looks promising that we can run this motor without
FOC as well.

Why am I trying to manoeuvre around FOC?
a) It's not exactly straight forward, quantities like Id and Iq are very
abstract
b) It needs the current sensors which slip control does not

There have been a number of refactoring approaches, like separating
motor and vehicle control, using the QP framework etc. which might make
the software simpler and more readable.

The firmware is on the github repo, the remaining stuff is in a zip file
on my web page.

I have also registered the domain openinverter.org and was picturing a
wiki, a forum and some shop software to go on there. Unfortunately I am
lacking the time to work on all that. So if the old theme wants to
rejoin and put some life into the project again that would be wonderful.

All the best from Germany,
Johannes
