Modeling Physical Systems, An Overview

This video sets the stage for the topics that I want to cover over the next month or two. This is an overview of how you go from a physical system to a linear model where you can design a linear control system. Once you have a working linear controller you then need to test it in your nonlinear model and the real physical system.

Once you understand how we use linear models and simulations you will have a better appreciation as to why we place so much effort and attention learning how to model a system.

If you have any questions on it leave them in the comment section below or on Twitter and I'll try my best to answer them.

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!

These tutorials were great for a control systems class I had! We controlled water levels in a coupled tanks system.

i watched this like 4 times and i just loved it please post more videos soon!

Great job and great video! In particular i appreciate the adjusted tempo of the writing and how well it is coordinated with the sound/comments. And also everything is so neatly illustrated. These videos are the best i have seen of their kind. :-) Looking forward to the continuation on how to model physical systems!

ever the best explaination of control system

Nice to see you again making videos!

Just started my first bona-fide control project, strapping a $6 webcam to a dream cheeky USB nerf turret to convert it to a face tracking sentry.  :)

It sorta works now, but only if you move realllly slow.  I can't wait to apply some of these lessons to introduce some modeling and a real control loop.  I need to ramp up my defenses at the office. haha

This is a excellent video. Thanks alot!

[dobkhnistheking]

come on Brian! please get to designing the physical system i can not wait to watch that!

[GLUEALLSTAR]

Hi Brian when will you do the video on developing a model, I am really looking forward to it. by the way really great explanation.

[Mohammadalhashash]

Awesome .... that was so helpful, ty

[johnalamina]

Love the illustrative notes on the videos anyway to download as pdf?

[Cagedope]

Thank you for the great videos. Where are the nyquist plots videos?

[hamadmusabeh]

man were were you when i was in school, , ,
we took math in "class" with not relation of real world, , i could not make any sense of the class.

i hope you can do a basic video of math stuff, like integration and differentiation as a re-fresh.

thx for the videos

Hi Brian, great videos! It's really helped my understanding of content in my controls class. Can you recommend any additional resources to better understand Nyquist Stability Criterion and lead lag compensator design. Thanks again!

[ptfreelancer]

Great videos!! Do you plane to make a video about Nyquist stability criterion?

[TheAhmedMAhmed]

I hope your lectures are comprehensive.

[socialogic]

Can you please make a video on state space...

Maybe I'm a little late but I got a question. I'm having issues in formulating the transfer function of a project I'm working on that is a PID solar tracker that moves with a servomotor but we did simulation and got the data of the servomotor position and the time. Can I get a transfer function with just that data?

[jsbc]

you haven't explained nyquist criterion :( Great vids!
