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

AE511: Being able to use the linear system analyzer to plot multiple graphs is incredible. Nice to see that the tool designer prepared this well for quickly comparing multiple systems at once. Thank you for highlighting it here.

[@ChristopherLum]

It really does make it so much easier to visualize the responses

[@TuanTran-fs8ll]

AE511: Very cool analysis tools. Thanks for the MATLAB demo, it is very helpful. Tuan Tran

[@bradleyparks1982]

Great tutorial for the linear system analyzer in Matlab!

[@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.

[@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!

[@TranPham-o7x]

AE511: these are great resources, much appreciated.

[@ChristopherLum]

Glad they are helpful!

[@bsgove]

AE511: Very useful tool!

[@KhoaiNguyen160]

AE511: Thanks for the super useful lecture

[@melissawells8133]

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

[@jcguo582]

Great vedio

[@selamhendrix5252]

thanks for explaining all the steps

[@burningbush2009]

AE511: This was an extremely helpful lecture, thanks!

[@ChristopherLum]

Glad it was helpful!

[@belkimeriem7706]

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

[@hossameldin2912]

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

[@wes1588]

Great video!

[@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

[@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.

[@TriMartz-f4x]

[AE511] Really handy tool!

[@richadubey7902]

Hello Dr. Lum can you please let me know what are learning benefits, joining as PhD student. Also your video are a great help. Thanks

[@ChristopherLum]

Hi, to be honest, I'm actually able to interact more closely with fan on Patreon (www.patreon.com/c/christopherwlum) . Feel free to join over there and if you message me I can more easily see your direct messages and can respond and interact with interested stakeholders on Patreon. Thanks for watching!

[@LilanieAlfredaAbdur-Rahman]

AE511: Thanks Dr. Lum but quick question: Is it possible that I missed where you may have told us to skip the time stamps for the first 2 Matlab functions?

[@ChristopherLum]

Hi Lilanie, can you help me understand a little more, where did you hear that we should be skipping portions? Do you have a timestamp somewhere?

[@alanlee4326]

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?

[@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?

[@sethwhittington28]

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

[@smithdeagle1010]

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

[@MattAero]

AE511 - Thanks for the lecture

[@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?
