how does this approach work for MIMO systems where the transfer functions are matrices, and so the order of multiplication should never be changed? For this reason, even in the introductory/basic control theory course, our professor teaches us that we should start from the output (right-hand side) and work our way to the input, as this matters for matrices.
Waste of my time. Professor requires us to do it by hand and without matlab. Should add the fact that you're cheating with software to the video description.
Finding the transfer function of block diagrams by hand can be done, but it is a *not so useful skill. Finding the transfer function by hand may take more than 10 minutes and requires redrawing the diagram multiple times, increasing the likelihood of making mistakes. Here I show an approach that can be performed in minutes and is very easy to understand.
@@theelectricalengineeringst7231 I completely agree with you. However, most people who are looking this particular thing up on CZcams are going to be college students who's professors require them to do it by hand for exams. You have to keep this in mind and show both methods. In industry, it is very commonplace to use software. However, in university, it is almost exclusively done by hand.
@@theelectricalengineeringst7231 Personally, I think the way you showed it with the nodes is super-useful. After that, it comes down to algebraic skills, which is definitely not USELESS. It'd be like saying it's useless to know the times table because calculators exist. Also, once you find all the nodes, there's no need to redraw the diagrams.
You made a mistake entering s3 into your sys, it should be =s2G2+yH1 not +yH3.
You’re right. Good catch!
Wow. I got it! Treating them as nodes make so much sense! Thanks
Good to hear. If you would like another topic covered please let me know.
Thank you so much bro! You really made my life easier!
please , can you help from where did u get the question like book or site? it will really helpful.
I like using Mason's gain formula

very helpful! thank you
Awesome tutorial. May I know what software you’re using to solve it?
It is called Maple.
What software did you use?
Name of app you're using?
If I were to remove G4 and replace S4 with a circle thingy, what would the equation for Y be? thank you in advance :)))))ummer
Y = S4?
How did you see that s4 is a node? Why isnt it a node before h1?
Any signal between two blocks is a node.
What software is that one? Thank you
MATLAB
👍

@@nicholaslozuk4788 okay, so how would you do it by hand? what's a good video for this?

The audio of this video is really poor
Just turn up the volume.
Useless crap 😞
