This video attempts to provide an intuitive understanding of concepts like stability and stability margin. I briefly describe both of these topics with examples and explain how you can artificially generate stability in a system by adding a closed loop control system.
I will be loading a new video each week and welcome suggestions for new topics. Please leave a comment or question below and I will do my best to address it. Thanks for watching!

Who's still learning from these great videos in 2020 ! 😀
Seems like teachers really like you and your content, my teacher for online school has pointed us to your videos a few times already
You're amazing sir I will donate as soon as I will start earning. Your lectures are making it interesting as hell! keep up the good work and don't ever stop.
If our goal is always the very top of the mountain, then my actuators and sensors will be the intermolecular forces of a bit of glue.
However, for a more general sense, I would likely be designing the ball itself to navigate, so probably GPS and an internal weight.
Thank you sir very much! I'm an undergraduate student from China. I feel so grateful that I can learn such great and free control system course on youtube. Teaching with PhotoShop is really cool! You make some knowledge point like convolution so clear and easy to understand.
Sir can we use a camera tracking system for the ball on the mountain😄
if an impulse input produces constant output, will the system be considered stable? thanks
The explanations regarding the stability was simple and accurate. Great job!
0:26 Clarkson vibes… 😀
Eureka, Brian! Consegui, pela 1ª vez na vida, entender gráficos de Estabilidade e Instabilidade, em relação ao tempo t. Obrigado!
Great class! You are the best teacher that I have seen!
Thanks Brian, great help.
I would glue the ball to the top
I would use a system of weights with a balance engine inside the bol.
If you want the ball to stay on top of the mountain at all times, just nail it to the ground uwu
Best control system lecture
Not only are your explanations extremely clear, but your sketching skills are incredible 😀
How about building electrostatic charge so that ball will always be attractive towards top of curve, and be repelled by any deviation caused when getiing closer to instability, making the system as a capacitor..
thanks!!!!!
I wish my curiosity lead me to this channel bit earlier
I am in the endgame of the semester now, I will watch it anyways (after the tests )but would've loved to understand the concept rather than just solving everything without intuitivation in the test
Someone explain me the Dart Concept!
Thank you, i understand it a lot.
some magnetic field which requires no sensors
I will rotate the whole Mountain if it's a globe as an actuator, and use a Camera to track the ball.
Its very clear 🙂 Love this analogy! Thanks!
we can use electro-magnetic to return the to the top
cute drawing style, LOL, great video!
first of all this is extremely helpful , thank you very much
secondly, i wound use a curved up (positive slope) slides that would convert the unstable system into a stable one like the example of stable system, and that is triggered by a sensor when the ball comes near it
Amazing
Hi, I was a little confused on why shooting a dart backward produces an unstable system… The motion of the dart is the same (except its flipped) to the stable system
Amazing stuff
Very great video, very intuitive. I have one long pending doubt on small signal analysis, Is it possible to include one intuitive video on the meaning of small signal model, and also can you explain the intuitive link of small signal model to the control problem of keeping the ball on mountain top that you have described in the above video. Thanks for the video and thanks in advance
I would use a camera as sensor, image processing tool as controller and an accelerating hill as plant
Wow , you are ammmmmmmmaizing sir . One video on lyapunov stability please sir.
practical explanation.now i can relate my theory course with practical phenomena. great u r sir. thanks a lot.
I used to use matlab and design control systems daily. You made clear a lot of concepts that had been hard to grasp at the time.
Sir, can you make videos on Modern Control Theory please???
shooting off a first idea to that question which popped up in my mind. Maybe I would try to introduce electro-magnetic surfaces on my mountain and ball so that as soon as it starts tumbling down either side, a similar polarity can be induced and the ball would be repelled to come back to the equilibrium point.
God bless you dude!
