Finally I understand state space. I have an exam tomorrow and you're a life saver! I believe in the A matrice, the bottom left should be -(R1+R2)/L1.

Good eye, I noticed it too. :) This is my first day with state-space stuff, looking to binge-learn the material.

Yup hes missing a negative there.

Just started Control 2 today as part of my undergraduate degree in Electronic and Computer Engineering, you have no idea how much this has helped me. I appreciate the time and effort you put into making this video, from the bottom of my heart, thank you.

I just learned more than I did in 3 weeks of class. Nice format and very well taught.

So glad we can help! Thanks for your feedback, 808chrispy. We'll take a look at it ASAP.

+UConn HKN Did you get a chance to look into '808chrispy' comment regarding the coefficient in the bottom left of the A matrice?

@rodericksibelius8472 2 жыл бұрын

As an experienced Electronics Technician for 40 years, with only a 2 year Technology degree level of Mathematics and no calculus / or confusing matrix algebra learning, I'll just build a circuit and use a 4-channel oscilloscope and observe the behavior of the circuit in the REAL PRACTICAL WORLD and write a procedure or a technical paper using only ALGEBRA and Trigonometry on my results. This is so confusing to me, and I Have great RESPECT to all ENGINEERING Physicists who can ACADEMICALLY DERIVE ALL THOSE MATRIX EQUATIONS on PAPER, AWESOME VIDEO!.

Good job. I just wanted to point out that at 13:45 you forgot the negative sign of the coefficient of X3. Check the X3_dot term for the inconsistency.

like Mr. E. Befula stated, but he was speaking of VR2 which might have threw you off is you forgot to add VR2 to the C matrix. VR2= R2X3 therefore the third value in the output equations C matrix should be R2-R1.

@6busted9 6 жыл бұрын

Correction... His C matrix is correct...R2X3 gets canceled with the addition of L1 xdot3

Is he writing backwards?

@arabniga 5 жыл бұрын

No he actually writes normally then they flip the video so that it doesn't look reversed for us. That's why the pen is in his left hand.

@GLu-tb1pb 5 жыл бұрын

interesting how you merely use KCL and KVL to resolve the problem. Didn't think it was that simple.

nice method you have here

@kalayouberhanu9410 6 жыл бұрын

in the D matrix, i think the last term to the left should be -(R1+R2)....OHHHH SORRY IT IS CORRECT CANCELLED OUT R2-R2=0... TANX LOVE YAAA

Hi and thanks for commenting! We write on a piece of glass and shoot the camera at a mirror so that it reflects what you see when looking at the back of the piece of glass. You can learn more at lightboard.uconn.edu ~Andrew

@edwardbefula2666 7 жыл бұрын

Where is VR3 represented on the output matrix cause it seems like you left it out

@UConnHKN 7 жыл бұрын

VR3 may not be explicitly solved for in the matrix, but you can find it from the variables that were solved. In order to "solve" a circuit, the objective is not to solve every possible value, but to solve the minimum number of variables simultaneously so that the rest of the variables can be solved with known formulas! ~Andrew
