System Block Diagram Question

  1. Oct 23, 2009 #1
    Hey guys,

    I have this questions that I need to solve. I have to shrink the massive block diagram down so that I end up with a close loop Transfer Function at the end.

    I have shrunk it down a fair bit but I'm stuck at the moment..

    1. The problem statement, all variables and given/known data

    2. Relevant equations

    Jt = Jm+N*N*JL

    Bt=Bm+N*N*BL

    3. The attempt at a solution
    This is what I have ended up with, after some moving around..

    I'm mainly stuck on the Kt, Kb feedback loop...

    Thanks heaps....
