H Infinity and Mu Synthesis | Robust Control, Part 5

Показать описание

This video walks through a controller design for an active suspension system. Actually, we design two controllers. For the first, we use H infinity synthesis to design a controller for a nominal plant model that will guarantee performance but not necessarily be robust to variation in the system. Then we build an uncertain model like we did in the last video and design a robust controller using mu synthesis.

I have been waiting for this demonstration for H infinity control for long time

NoNameFound--years-ago

Mr.Brian Douglas, I really can't find a way to thank you for your huge help and support in control field, I have finished my Bachelor's degree in mechanical engineering and I am almost done with my Master degree in mechatronics system and you were the best reference for all control topics, nobody can explain these topics in such nice and clear way direct to the point and also giving examples using MATLAB to proof the concept of the topic.
I would appreciate it if you could do something related to adaptive control and autotune because these topics are not clearly defined among youtube.
I wish you to have more success in your future life.

You are the real mvp in the control field, it is just so amazingly easy to understand once you explain it

I had a course on the control of MIMO systems. This stuff is amazing

First off good work -- we usually teach this in 4th year EE.

FUTURE IDEA: Describe sliding mode control design, its stability analysis and non-chattering implementation via stateflow. Next, go all the way and describe stochastic hybrid control with wiener processes (unbounded stochasticity) and its convergence/stability analysis. A lot of biological processes (including human organ) control is via stochastic hybrid systems -- experience in medical device design/control for cardiac arrhythmias and GI motility disorders.

Just one caveat, stateflow/simulink will choke when simulating hybrid stochastic Wiener processes via Euler-Maruyama.

This is so good video about Robust Control, now I understand the whole concept I have been struggling with. Thanks alot!

It might be worth mentioning that H-infinity does have the downside that the order of the generated controller can be quite high (I believe it is equal to the order of the plant plus the orders of the weighting functions).

Great Video. Can anybody explain how the parameters are chosen for Handling Target and Comfort Targets?

mohamednihalnadvisaleem

thank you very much.
I have a question regarding Wact, you have said that putting a high pass filter on the actuator is going to penalize high frequency controller commands more than low frequency, isn't it the opposite ? or i didnt understand it

hakemass

Wow, nice explanation! Thank you so much.

how to understand mathematically? Do you have good source for H-infinity control theory? please recommend thanks in advance

sayandey

Can someone tell what’s the benefit of the generalized plant representation? Couldn’t find any intuitive explanations

Can anyone suggest a good book for Robust Control (Mainly Related to H-infinity)
and Also Great Explanation

how we can fo r example compute and do some simulation of H_infinity Control of Two-Dimensional Systems with matlab

Hello, a very nice demonstration of the H_infinity control design. How does the mu synthesis perform compared to a robust controller where you model out the uncertainty (Delta) and use H_infity and the small gain theorem to provide robustness.

MrMD-ov

Can you suggest some references where to study about H infinity and mu synthesis?

paolzpk

Hi! It's a really great video! But it's so fast, particularly for nonnative speakers. Of course, if you're familiar with this topic you can swallow it and digest it, otherwise choking...

haligali

Can anyone help me. Which value record the value gain K of H-inf ?

chiro

any direct paper for H-Infinity controller on full car model?

deepak_nigwal

Can I get your channel, good explained
