ME207 DC Motor Model Equation Derivation 

Thank you, Matt. You presented materials that I was exactly looking for. Just subscribed and hoping more videos to come.

I'm so glad to find this video. Struggling on controls hw for a couple weeks and it's finally coming together. Thank you!

Thanks Matt, you deliver an awesome lecture, things are well explained. I wasn't able to implement this model on MATLAB due to the mathematics involved but after watching your lecture, now it's easier to do so.

goat vid, just helped me with my hw, bless this man

Hi Matt, really good video. Just a question, can you describe the units in the mechanical equations, I can not understand how is everything canceled correctly and balanced in the equation. For instance I will have radians for theta and the Torque is only N.m

Thank you Mr. Matt

What if you want to model DC motor system using Lagrangian technique

On the surface I thought I understood how dI/dt goes to zero with a motor at steady state. But then I considered how the commutator sends current to each winding for only a short pulse of time as the armature spins. Even at steady state, individual coils get continuous pulsations of voltage and current, so dI/dt is not zero at steady state for individual coils. So, why don't we see more prominent inductance from a motor even at steady state? Does the rotation of the armature against the force of the magnetic field consume the energy of that inductive kick? Or, is it better to think of rotation as generating backward voltage by movement of the coil through the field, cancelling out the repetitive inductive forces happening in each individual coil? Or, should I be thinking of the motor as a whole, with some coils discharging while some are charging, all sharing those reactive changes so the net effect is a small inductance?

does it possible to make a third order model of dc motor?

thank you so much it's been very useful

Thank you. you explained it very well.

Really excellent video!!

Excellent! presentation, you are not comparable must of our lecturers Naija will be great

I fail to understand replacing s.theta(s) with theta'(s). Can someone explain?

how to calcultae if the voltage increase?

Fantastic, do you have a series for this lecture?

Hi sir can you able to teach me how to rearrange DC motor equation

Thank you for the lecture. Please, tell me, are you writing on a transparent board from right to left? How long did it take you to learn to do that?

Thank you Mr. Matt may I ask you for mathematical modeling of direct control of BLDC motor? , please

Thank you so much!! 👏

thank you sir! :D

why are the k (Torque constant, Kt) in the mechanical system and k in the electrical system (back emf constant, kb) used as the same "k" with your k^2?

can someone add english subtitle please

Thank you

how do you write on the screen thanks for the video

hey Bra ! what about the load torque which oposes the electrical torque ??? you only stated the frictional Torque "Bw"...the correct equation of the mechanical side should be, Te-TL-Tw=J d/dt (w)

Thank you :)

I think your graphical betwen speed and voltage start with speed zero for v(0)

at 19:14, why does the s*theta(s) not come through to the equation on the right? edit: nevermind haha, you notice it a minute later

You are handsome and smart.

The content is great but the squeaking marker makes this unwatchable.

I want to ask you about the subject of electromechanics, if there is a specific source that I can study on, a source from the United States University. Because I am not a university. And if I can contact you to inquire if you have an Instagram or Telegram account.
