Re: Ifoc algorithm

[Amândio M. R. C. <ama...@gm...>]

I studied in the master of electrothecnic and computers in Oporto,
Portugal, and for some reasons i didn't finished, but i decided do
something beyond the work with my family in the vineyards.

I saw that the Tumanako project would be good to learn.

My intentions are converte a car or a pick-up to electric, and as i'm
almost unemployed, perhaps, if i find someone to colaborate, make some
business with it.

The schematic that i implemented is one that are in the book "VAS P.,
sensorless vector and direct torque controle , Oxford university press, New
York 1998", "schematic of the rotor-flux-oriented control of a voltagem
source inverter-fed induction machine".

The motor parameters that i used i found in a papper, 22kw, 4 poles.

The PI values was with some attempts, but i'm thinking in make a genetic
algorithm to tune it. I don't see another way, i have no experience, like
Laplace.

The calculations of the rotor time constant i followed yours wiki
references. It requires some hard computation and must be implemented with
concurrency in the microcontroller. My experience with embedded control is
very little, i must learn.

The calculation of the rotor magnetisation current i followed the
"Freescale" papel and others.

I'm searching for a real cheap motor with all the parameters known.

Johannes is not much interested in the ifoc and i undertand, V/f is much
simpler and the efficiency, maybe is not much different.
