Block Diagram Reduction (Solved Example 2)

[@gregoiredesclee9292]

2nd Problem: 1) split the right-most adder into the rest of the block diagram + a negative feedback loop which can be solved as (G3/(1+H3G3)) 2) move the branch from before G2 to after G2, and compensate with gain 1/G2. This puts two branches in parallel whose overall gain is (1+1/G2). 3) now the left hand side is two nested negative feedback loops. The inside feedback loop solves to G2/(1+H2G2). The outside then solves to G1G2/(1+H2G2+H1G1G2). The total comes from multiplying the results from 1) 2) and 3) together.

The answer for the first homework problem__ numerator= G1G2G3 and denominator = 1 + H1G2G3 - H2G2G3 + H3G2G3

[@Abvht1656]

Same

[@briankimani8335]

simplify denominator = 1 + G2G3(H1 -H2+H3)

I really appreciate U now can do any problem concerning block diagram algebra🎉

[@Divyanshusrivastava24]

Ans 1)G1G2G3/(1+G2G3H1-G2G3H2+G2G3H3) Ans 2)G1G3(G2+1)/(1+G2H2+G1G2H1)(1+G3H3) In second problem, shift the take-off point before the block G2 after it.Then simplify it.

[@Tejaswini01212]

Hey how did you solve that 2nd example..?

[@Divyanshusrivastava24]

@@Tejaswini01212 Firstly split the 3 input adder into two 2 input adder.Then shift the take off point before the block G2 after it.Then it can be easily reduced.

[@Prakash-dr2es]

@@Divyanshusrivastava24 sir,after shifting branch point before G2 then block becomes 1+G2 right

[@Divyanshusrivastava24]

@@Prakash-dr2es After shifting of take off point,a new block of gain 1/G2 comes according to block reduction rules.Then after further solving you get a block of gain 1+1/G2

dr very thanks to lecturing

Thank you very much!

[@eulendabasetsana1938]

On Step 2 of this problem, will I be wrong to consider G1 and the positive feedback as a closed loop?

Q.1) Ans:- G1.G2.G3/G2.G3.H1 - G2.G3.H2 + G2.G3.H3 -OR- =G1.G2.G3/G2.G3.(H1-H2+H3)

wrong answer.. add 1 in the denominator

Block diagram reduction? More like "This is great instruction!" Thanks again for making and sharing all these videos.

[@amandhakal8939]

The answer came out to be (G1G2+G2)/(1+G1G2H1+G2H1+G2H2) while using Mason Gain formula. Why is it different?

[@tsumokd7616]

Same here. I also got (G1G2+G2)/(1+G1G2H1+G2H1+G2H2) as the final answer while simplifying this problem

Why not work through it yourself first, comment what you got, and see if other people agree? That way you can get more practice, and the answers you receive will be more meaningful.
