SimPowerSystems, AC6 electric drive explanation

Hello,

I'm working with the AC6 electric drive. I didn't find a lot of information about the drive in the Simulink help.

In fact, I would like to understand how the Vector controller was made. I tried to play with the Clarke and Park matrix but I didn't get the same equations as the one on the vector controller. Does anyone have more informations about that or a link that explain how it works?

Thanks

The documentation provides a schematic of the vector controller:

You can also look under the mask of the block to see how it's implemented.

HTH,

Thanks for your answer but that's not really what I'm looking for.

I'm searching for theory. More specifically, how can I obtain the equation that are under the mask of the different blocks.(for example Why I=2/(3*nb_pole*lambda) in the T->I block...)

[Arnaud Miege]

Have a look at the references listed in the documentation:

[1] Bose, B. K., Modern Power Electronics and AC Drives, Prentice-Hall, N.J., 2002.

[2] Krause, P. C., Analysis of Electric Machinery, McGraw-Hill, 1986.

Answer 3

[Debz]

Thanks, now I have a better understanding of electric drives.

I might be wrong but after looking at the "modern power electronics and ac drives" book, I did not obtain the exact same equation on the dq-abc block. For example on the block we have: ia=-id*sin(theta)+iq*cos(theta)

Thanks to the book I found ia=id*sin(theta)+iq*cos(theta)

I also have the same kind of problem for ib. But since id=0 in the ac6 model, the problem disappear and is not important.

But for my own understanding I would like to know which one is correct.
