Paul and Sabrina's Cheap 3 Phase Inverter (AC Controller) with Field Oriented Control

[LouMan]

It always happens when you don't have any money!!!! figures....

[jackbauer]

Ok this may seem like a strange request but can someone confirm to the world that I'm not a Russian hacker / fraudster?

[BogdanT]

))) what's the catch? Where do we confirm? Are you getting sued for reverse engineering? )

[Piotrsko]

You ARE Irish. That's scary all by itself.

I can confirm that you are not Russian, and not a fraudster ... I'm not signing off on the HACKER part ...

To what address should this message be sent?

[BogdanT]

By the sound of it, we should send our letters to the Director of J2 ))

Another interesting job..a controller but using Arduino plataform (Arduino Due that is more powerful than Arduino Uno/Mega) and using direct self control .
I don´t know avantages between direct selft control against Field Oriented Control ..someone knows ? :

I have not read about Direct Self control. As far as I know, none of the commercially available AC Controllers use this method. Or perhaps they do and they call it something else?

The harmonics look nasty. I wonder if the torque is better than flux vector control.

The AC Controllers we use at work are all variants of sensorless flux vector control. No encoder. Implied position is calculated from back emf of the motor so an encode is not required. The control is not as good as if you have an encoder, but it's good enough. Not installing an encoder, and not fixing an encoder .. is PRICELESS!

I know that self control does not work very well. At least when it comes to cookies around the christmas season. I can also confirm that jackbauer is not those nefarious things.
