Time Domain Analysis with Matlab: Using the Linear System Analyzer

In this video we explore various Matlab functions and workflows to perform time domain analysis of a dynamic system. This includes the use of ‘tf’, ‘step’, ‘lsim’, and ‘linearSystemAnalyzer’ functions/apps.
Topics and time stamps:
(0:48) - Explain example system
(12:40) - Setup problem in Matlab
(13:03) - Using the ‘tf’ function
(18:12) - Using the ‘step’ function
(21:27) - Using the ‘lsim’ function
(24:38) - Using the ‘linearSystemAnalyzer’ function/app
(33:24) - Higher order systems
(36:29) - Summary and conclusions

In case it is helpful, here are all my Control Theory videos in a single playlist th-cam.com/play/PLxdnSsBqCrrF9KOQRB9ByfB0EUMwnLO9o.html. Please let me know what you think in the comments. Thanks for watching!

Great tutorial for the linear system analyzer in Matlab!

[@seanstocker]

AE511: Great lecture. It was very helpful to have the explanation of the inputs and outputs for the different functions in an easier to understand format than the Matlab help.

[@ChristopherLum]

I'm glad it was helpful, let me know how the rest of the videos go!

[@wiloberlies9598]

Wow, thank you, so much great info in the past few days.....these are great resources, much appreciated.

[@ChristopherLum]

Thanks for watching, I'm glad you enjoy them.

[@jcguo582]

Great vedio

[@burningbush2009]

AE511: This was an extremely helpful lecture, thanks!

[@ChristopherLum]

Glad it was helpful!

[@selamhendrix5252]

thanks for explaining all the steps

[@melissawells8133]

AE511 - Helped me sort through parts of reading the manual that didn't make sense for the program. Thanks!

[@wes1588]

Great video!

[@belkimeriem7706]

Thank you very much..but I was looking for the simulink linearizer

[@sethwhittington28]

AE511: This seems much easier than all the math we did last week to accomplish the same thing haha.

[@shanmukharao3452]

Video is helpful and kindly make video on 2-dof system with damped forced system on time domain or frequency domain....Thanks in advance

[@hossameldin2912]

Perfect! Can I modify the magnitude of the step input in linearSystemAnalyzer to be 1.5?

[@ahungryflyer]

AE511: I liked that we learned the functions in order of increasing complexity - do any of the three functions have the ability to automate the GUI interaction and output results? Or is some manual interaction within the GUI always required? I'm thinking of a scenario where you'd want to analyze a wide range of transfer functions with speed being of interest.

[@ChristopherLum]

My typical workflow is to use the GUI to do some preliminary testing but then rapidly move to script based programming as it offers more flexibility.

[@MattAero]

AE511 - Thanks for the lecture

[@prodigy803]

How do you analyze experimental data? Let's say you have the reference signal and feedback signal in the time domain measured from an oscilloscope. How do you derive the transfer function from those measurements to feed it into the linearSystemAnalyzer? Or experimental data is dealt with in a completely different manner?

AE511 - On the blackboard for TsTilde, missing a negative in front of the ln.

[@timproby7624]

[AE 511]
I assume it's possible to code the metrics so they output as data rather than having to use the GUI to solve for them?

[@nathanlipshutz3140]

AE511: Stupid question, but is u(t) a force or a displacement? It must be a force right?

[@ChristopherLum]

u(t) can actually be anything you want, it all depends on how you model the system. In some cases it is a force and others it can be a displacement (or anything else like an aileron deflection, etc.)

[@guilhermeferrari2562]

I want to make a quarter car program on matlab. How to make these result values become input in another function?

[@edwardsanchez2331]

ae511 good lecture

[@smithdeagle1010]

may i know how the equation for steady state error is obtained at 9:00
