System Dynamics and Control: Module 13 - Introduction to Control, Block Diagrams

[@Gryphon018]

This presentation helped me to truly understand block diagrams- an issue I was struggling to grasp in my System Dynamics class. Thanks!

[@zepurkarkazian3654]

Thank you very much for sharing this video. You are a great teacher. I have much better understanding of the control system block diagram .

[@sHrG78]

Great video. Clear and detailed explanation.

[@omerosmanaksu5128]

Thank you sir, that was helpful.

[@nkosiphendulenkcinkca7347]

thank you I now have good understanding of simplifying block diagrams,,, you are great sir

Your video was so helpful and awesome!

[@phyozinwin]

Thank you so much. I have learnt a lot from your lecture

[@eduardoteich5892]

@Rick Hill In the cruise control example, what will happen if the error signal is zero? The output velocity V(s) should also become zero since V(s)=(K/ms+b)*E(s) neglecting disturbances, which means that the vehicle is in standstill and motor stop working!!!!

You are amazing, I wish you were my professor!

[@gihadgaming6194]

Y(s)/D(s)= forward/( 1 - loop ) right? 46:35

[@hillrickc]

It's not because even though the feedback signal entering the summing junction at the D input is positive, it is still subtracted at the summing junction where the R input enters. I try to step through the logic on the next slide if you keep watching.

[@nahuel3256]

@@hillrickc I was just wondering the same

[@김민제-q9f]

I have one question. What if i want to get E(s)/D(s) instead?? I found the loop disappeared.

Sir, Please reduce the humming noise. after a certain limit it totally creates headache. Please do the needful.

[@水韵-e5i]

At the 47min, the multiple inputs part: should the Gs be changed to -Gs when we treat the R=0

[@水韵-e5i]

+Binbin Cui sorry, I get it. The positive feedback will cancel the -1.

[@izzyAKAisra]

what book do u use again?

[@hillrickc]

I use a variety of sources, but the book that most closely follows my lectures is System Dynamics by Ogata.

[@izzyAKAisra]

Can yo do more examples on Fluid Systems and Mechanical systems models? I love your lectures by the way. Thank you very much!

[@tolgaakdogan7842]

Rick Hill I think Conrol System Enginners byNise is also very simillar

[@hillrickc]

I agree. Nise is a very nice book, but it is a bit more focused on control design than these lectures ... here the focus is a bit more on the modeling.

[@tolgaakdogan7842]

i understand. I am an eee, not control engr. so my main concern is first, second order systems i guess. However i get stuck on an example. Can i take your e-mail?
