The previous two videos showed a few different ways to quantify how robust a system is to model and plant uncertainty by looking at how much input and output variation it can handle before it no longer meets requirements. In this video, we show another approach. Rather than apply variation to the model as a whole, we apply it to the individual parameters within the model to determine how robust the system is to parameter uncertainty.

You are the hero of control theory.
Great work as usual Brian, please do something similar for nonlinear control, we would love to start using nonlinear control Matlab tools, thank you very much!
Finally MAT lab decided to make awesome videos like old kan achademy videos :) awesome
Nice Work
Greetings from Peru! You re the best!
let me speculate, would there be a close form solution if the uncertainty is Gaussian
Dear Mr. Brian, I have a problem. We found robust stability using robstab. It gives 2.3 times that set values. So considering m2 set value is 1 and can be 1.46. But wcu value tells m2 minimum unstable value is 0.54. Why does not it 1.46? 0.54 to 1.46 values are system unstable or not?
Dear Mr. Brian, I have a problem. F = umargin('DM', [0.9 1.1], 10); % Gain varation 0.9 - 1.1 and Phase variation +/- 15 deg give an error message. Error msg - Unrecongnized function or variable 'umargin'
you're the best
BRAVO
nice
The Mass of the body is neither created nor destroyed. If it's so why do you vary the masses?

Because we don't know the masses with infinite precision. Manufacturing processes can only make the masses of the carts to within some tolerance (say, 1%). He's varying the mass to see what happens for different mass values that might not be exactly what we expected. Plus the carts might get pieces chipped off, or they might accumulate dust or rust. So even the same cart might have its mass vary over time.

In the case of an aircraft the mass vary because it consumes fuel
