Ok. Last Question. For K=1 and K_v=0, how do I use this transfer function in MATLAB to get the Root Locus or Bode plot?

Y=\frac{G1}{1+G1(1)}= \frac{K}{s^2+s*K*K_v+K}?

The output \theta goes back into junction, which gives a transfer function of 1? We're looking for \frac{θ(s)}{θ_r(s)} right?

Understood. Proceed by using rule 2 again and that's it? Looks like I was over complicating things. Thanks

Ok, I used the rules with some additional help from here: http://wolfweb.unr.edu/~fadali/ee370/Block_Diagrams.pdf and also here: http://www.youtube.com/watch?v=UFPhhS3MCiM To get this: What do I do with the inner negative feedback loop? Do I move Kv out? I'm assuming the outer loop...

That's the only thing I'm not sure of...the block simplification. There's so many rules and I don't know which ones to apply here.

Yes please.

I'm trying to get the transfer function of this rigid control system that uses rate feedback to stabilize it. Using k=1 and kv=0 Attempt at a solution. When kv=0, the rate feedback is removed. In the block diagram, I moved the pickoff point and used the cascade rule to get 1/s^2 and...
