hard problem: "feed forwards"

[rajabi_u]

1)what is feed forwards?
2)what are 3 inputs and 2 output for feed forward?
3)advantage voltage source from curent source?
4)what is mM=f1(imR,...);
5) isq=f2(imR,...);
6) isd=f3(imR,...);
7) usd=?
8) usq=?
9)what are names of each controller?and why did use 3 limiter?
ok
hope for all
!!!

I tink 3 input are:ωmR,isq,isd;
output are:usd,usq

well...
All I can say about this control block...
Is a quite difficult to me, I can understand the induction motor control is based on the measurement of speed (asynchronous), I mean, the flux controller and torque controller, are too based on speed and they depend on
I think the induction motor model (block) is based not on the abc axis. Is on the base of d-q axis
I think one must to learn and understand the park transformation to actually understand the all control block model about induction motor

That's what I think

feed forward: could be the oppsite of feedback, remember a typical loop control
