[QUOTE="icesalmon, post: 6465179, member: 302121"] [B]Homework Statement:[/B] Determine the transfer function of the block diagram [B]Relevant Equations:[/B] Equations for Block Diagram Algebra [COLOR=rgb(65, 168, 95)]Step 1[/COLOR]: I first started by reducing the inside of the block diagram of picture "bd" (the portion with G[sub]1[/sub] and the negative feedback G[sub]2[/sub]) I obtained [B]G[sub]1[/sub]/[1 + G[sub]1[/sub]G[sub]2[/sub]] [/B] I'll call this term "[B][I]F[/I][/B]" [COLOR=rgb(41, 105, 176)]Step 2: [/COLOR]Then I'm left with two terms feeding into a summing point: [B]F - G[sub]3[/sub] [/B] I'll call this term "[I][B]K[/B][/I]" I can reduce this diagram as I did in the first step: [B]T(s) = K / [1 - K*G[sub]4[/sub] ][/B] The solution, on the other hand, is [B][I]adding [/I][/B]G[sub]3[/sub] to F as indicated in the second picture I've attached "bd2" I am not sure if this is a mistake (to add G[sub]3[/sub] instead of subtracting it) or if I'm not seeing something. Any help is appreciated, apologies if I've left anything out or made my solution unclear in anyway. [/QUOTE]
