I just graduated with an engineering degree, I know all the theory, I can do the maths with my eyes closed... But what I was always missing was a global intuition of the big picture in control. A lot of the theory seemed disconnected in my head and far from application. This series has been great for putting it all together and has increased my understanding immeasurably! Thank you.
Don't worry mate. I graduated 10 years ago and felt the same back then. Now the only difference after 10 years is you will keep coming back to these videos but you will vaguely remember the math behind it. After all these years this is now nostalgic and relaxing to watch. Sad truth is that this stuff only exists in college or in hardcode hobbyists because most companies will buy solutions that needs to be tuned (based on this basic knowledge).
I am doing my Masters in System and Control after 6 years of my Bachelor's Degree. And these videos are most helpful in revising basics and dig into the advanced stuff. Can't thank you more. Extremely helpful.
This series is a pure gold for me! While finishing my computer science degree, but with high interest in robots systems, I totally needed this to grab the missing contents on control systems 💯
I am working on a project where we are developing a product. The product has to be cheap and therefore cannot have too many of those expensive sensors needed to control the system. When I was first told that these sensors are only for testing and cannot be used in the product, I was bewildered. Like how will I even control the system then. Now that I know the concept of estimators, it makes so much more sense.
Thank you Sir....I have seen the whole series and it have cleared lot of my concepts about control theory. Your videos are just great and your way of teaching complex things in simple manner is appreciable. Thanks Again.

Professor, I have a doubt regarding the LQR concept that is explained here. Why isn't there any reference signal to the system? So directly feeding back the controller gain to the system is sufficient?
Sir, I love u and Ur misses work. I think your team is doing amazing work by making your teaching freely available! Truly thank you. I am confused on how to input some thing to my system if the u=-kx. I have u which is a step input. Could you please clarify this for me. i get it, you are feeding the states not the input. the input comes to the left of ure -ku with a summation block so like y-uk into the system
What does it mean to “ estimate state x from measurement y “ ? Should we know x already since the first equation x dot = Ax + Bu is the equation to calculate the next state ? Or is there something wrong with my understanding here ?
watch the last minute of the video. In reality you will not have a perfect measurement of x to feed into your controller. The C matrix models what you can measure and the kalman filter is just one of many ways to estimate the rest of x needed to feed into your controller u=-kx.

Dude, you're amazing
I second that.
I am working on a project where we are developing a product. The product has to be cheap and therefore cannot have too many of those expensive sensors needed to control the system. When I was first told that these sensors are only for testing and cannot be used in the product, I was bewildered. Like how will I even control the system then.

I am super motivated on Full-State Estimation now, thank you!

You are doing a great job when turning complicated things into easy understanding. Thanks a lot!
Thank you so much. Now I can see the whole picture. I don't know why in universities they don't start with such a great intro as yours. :)
Thank you so much Sir, you make this course much much easier to understand, simpler and intuitive.
I laughed a whole minute about the pause before he realized he forgot the y. 10/10
Thanks for your videos, professor. I would like to know how this concepts scale into reference tracking.

If there is no reference signal, then the LQR is regulating to the origin. In this case the reference is "0"
Invaluable!

amaaaaaaazing
You write the equation for y based on x. Does it mean x after being updated with xdot? Because otherwise x would stay the same forever right?
What does it mean to “ estimate state x from measurement y “ ? Should we know x already since the first equation x dot = Ax + Bu is the equation to calculate the next state ? Or is there something wrong with my understanding here ?
