System Dynamics and Control: Module 4 - Modeling Mechanical Systems

Sehr gut

Can we get the pdf notes for your videos?

I'M LOST

hlo sir, nice explanation. Sir can you plz make a video on how to make FBD of 2-dof quarter car model and how to write governing equations with piezoelectric material in series with suspension spring and also consider the damping of a tire. Plz reply

I found gold!

The book you continuously refer to is the Conceptual Dynamics that you wrote correct?

Great teaching. Thank you!

wow i was struggling understanding this in an online class in my school
thank you sir for making it simple

God bless you sir

You are a wonderful human being. And you have the talent of breaking complex concepts into several simple parts. Many thanks for the great effort!

what a great work , you deserve to with the top professors in this field due to your simplicity in explanation

Thank you so much. This helps a lot!!

Great

i need lectures 1, 24 and 25

stickiness can feel good sometimes

i have learned more about Systems Dynamics, and differential equations in watching a few of you videos than i have learned from professors over the last 1.5 years

im a korean student who had been looking for this kind of explaination. Thank you so much !! :)

very good your video and its explanation, although it is in English and I do not understand rsrsrs I am student of engineering of automation and I am having a lot of difficulties in modeling of dynamic systems quarter car system, you could make an example of this with values ​​of the masses and constants of k, and c. Thank you very much in advance

As long as other things are assumed stationary and m1 is moving up

For M1 if you assume same analogy with M2, why not the two forces on the upper side of m1 are acting downward?

sir can you help on how to control sdof system with piezoelectric actuator and sensor

Amazing Rick, the way you simplify the complicated mechanical system .. I would request could you please explain similar fashion how to design the structures.

Thanks...great explanation!

Why don't you consider the masses of m1 and m2 into equations?

Thank you for this video, it's very helpful. I have a question though, how do you find the state space representation for a circuit with, say on displacement X there's a mass and maybe 2 springs(one in displacement X and the other between X and Y) and at displacement Y there's a damper (and the spring between both displacements) but with no mass? I don't know if I make sense, but what I'm trying to ask is how do we find a statespace representation for a circuit with 2 displacements but only one of them has mass

Set the speed to x2.

Trust me.

Hey guys I want tell u about grup in wahatsapp taking about control systems any one want come to my group send me in my number +218945680821welcome

Thank you so much
I love how you make things simple and easy
I love your explanation and the useful useful information that you tells us
professor you encourage me to learn and watch all your videos
a single videos is like a whole course but in one hour I really loved you professor
real professor

thanks for great videos

excellent
sir how to apply this control theory on practice basis..

I mean, how can I control any physical system by any microcontroller or microprocessor

Very nice and clear explanation. please let me know if we want to put a controller, It should be one controller between body of car and Tire, I want to know do we will have just one u(t) in our equation (in
our state space vector) as output?

Very helpful, thank you

how to design a spring mass oscillation system in which frequency change is minimized w.r.t change in mass .

Hi Rick would you share a contact mail for discussion purpose?

Whats the name of the book that I can find more example?

Thanks sir, that was a lifebuoy :) By the way if you re-upload the video with noise reduction to kill background hum it will be flawless :) Regards...

Thank you. Great job.

There's a constant low frequency humming in your videos that is really uncomfortable on the ears. Had to adjust my equalizer to remove all lower frequencies to be able to listen to this video.

what book are you using rick?

With the quarter car suspension, do you derive a transfer fn for this example anywhere in your videos

thanks you sir, would you please make a lecture about dynamic vibration absorber?

Thank you...This actually saved me from a quiz.

Perfect  teaching. Appreciated!

really clear and helpful!

Great!

Great lecture

wonderful

Thanx for uploading these videos. May you please upload model 15 of these lecture series.
