Thank you so much for these videos they are so informative and have been the only resource that has finally got my head around control!! I have been so daunted by the subject all of this year at uni having tried multiple textbooks/notes/videos all of which have left me more confused. Now I quite enjoy the topic thanks to you and I won't (fingers crossed) fail the module 😂😅 So much appreciation, thanks again

AE511: I appreciated the methodical explanation of each block diagram modification - plus an example at the end. This came in handy to check back on while completing the homework. It had been a while since I had last worked on any block diagram algebra.

Okay it would do me a lot of good if you could tell me the full name of FE so I can look it up and find maybe what the exact name of my course, but in English. The exact translation would be: "Systems and controlling (steering)" really can't find nothing. The whole course contains: Bode Plot, Nyquist Plot (Diagram), Laplace transform, mathematical models (you know Spring, Damper and Mass & make a block diagram of that), traces (don't know what you call them) and pretty much that's it. Could you give me a name of a course which contains that material? It would be much appreciated, thank you.

Quick question: at 52:00 you noted the extreme importance of the opposite sign. Why does that matter? Thank you for the awesome lectures!
@carultch
Жыл бұрын
For a forward transfer function G(s) and a feedback transfer function H(s), with negative feedback, the combined transfer function is: G(s)/(1 + G(s)*H(s)) If we switch to positive feedback, we get: G(s)/(1 - G(s)*H(s)) The sign in the denominator is the opposite of the kind of feedback you have. Here's the proof from first principles. Assign input X(s) and output Y(s). Assign point P to be just before the G(s) transfer function, and point Q to be just before the negative feedback connection. This means X(s), P, and Q are related as such: P = X(s) - Q This also means that Y(s) and P are related as such, as well as Y(s) and Q: Y(s) = G(s)*P Q = Y(s)*H(s) Three equations, three unknowns (P, Q, and Y(s)). Combine equations and solve for unknowns: P = X(s) - Y(s)*H(s) P = X(s) - P*G(s)*H(s) Shuffle P-terms to the left, and factor: P + P*G(s)*H(s) = X(s) P*(1 + G(s)*H(s)) = X(s) Isolate P: P = X(s)/(1 + G(s)*H(s)) Substitute in equation for Y(s): Y(s) = X(s)*G(s)/(1 + G(s)*H(s)) Resulting combined transfer function: Y(s)/X(s) = G(s)/(1 + G(s)*H(s))
