I)
II) Shifting of take off point after a block
III) Blocks in series
IV) Eliminate feedback loop.
V) Shifitng take of point after a block
VI) Blocks in series
VII) Eliminate feedback loop.
Now simplify,
C(s)K(s)=G2.G3.G41+G3.G4.H21+[(G2.G3.G41+G3.G4.H2)∗(H1G4)]
C(s)K(s)=G2.G3.G41+G3.G4.H2+G2.G3.H1
=> VII) Becomes,
VIII) Blocks in series:
IX) Eliminate feedback loop and simplify,
C(s)K(s)=G1.G2.G3.G41+G3.G4.H2+G2.G3.H11+[G1.G2.G3.G41+G3.G4.H2+G2.G3.H1][H3+G3.G4.H2.H3G3.G4]
C(s)K(s)=G1.G2.G3.G41+G3.G4.H2+G2.G3.H1+(G1.G2)(H3+G3.G4.H2.H3)
C(s)K(s)=G1.G2.G3.G41+G3.G4.H2+G2.G3.H1+G1.G2.H3+G1.G2.G3.G4.H2.H3)
∴C(s)K(s)=G1.G2.G3.G41+G3.G4.H2+G2.G3.H1+G2.G3.H3+G1.G2.G3.G4.H2H
