Hi Brian, I cannot emphasize enough , how thankful I (and for that matter other hundreds of people) am (are) for your videos. Looking forward to the continuation of this series. Best to you!
Your videos are incredible Brian! I very much enjoy them all. You are among a few people I've ever seen that has such a deep understanding about the underlying principles of control. Thanks a lot and keep up the excellent job!
Brian, I cant begin to think how I would be doing in my controls systems classes without your content! keep up the great work. You really do make every concept of control systems less daunting for me and my classmates!
Brian, you are an amazing teacher & a fantastic artist! I really appreciate you putting the time into making these videos. Control theory is so difficult for me to wrap my head around, but somehow you make it so easy to understand.
They never really explained prewarping at my university. They did developed their own tool which automatically warps each filter component at the corresponding frequency, so I always took that for granted. But it is nice to know what is actually going on. PS: that tool also shows you the modulus margin of you plant with designed controller, but from searching online it seems that hardly any other university uses that margin as well.
Heey..I think I got the chance this time to thank you since the video is just uploaded yesterday, you saved my first semester with your classic control playlist :-) YOU ARE AWESOME REALLY, and I hope you can ends the discrete one soon cause I have a digital control course this semester: 'D and thank you again you cleared a thousands of concepts in both control and signals to me, best of luck
Hey Brian, great video as usual! Out of curiosity, what's your occupation? Most likely a controls engineer, but can you enlighten us with details about the specific industry or products you work on?
w-transform is another name that is used for the bilinear transform. w-plane also looks like the s-plane . But I guess your warping method provides a more intuitive understanding on how the poles are really moving due to warp.
I am now confused when you took T=2 and said sampled frequency=1/2 and Nyquist Freq =1/4. I studied that Nyquist Freq is 2fmax so it should be 1 i.e 2π rad
To convert a continuous domain TF to discrete domain - What are disadvantages of sampling H(s) at discrete frequencies and using invfreqz in Matlab rather than using bilinear transform?
Are you continuing these videos? And do you know of any other good resources for discrete control specifically dealing with state space methods? Thank you!
Awesome video man ! btw, did you hear about the rumors of state space ? they said that a guy called brain will make it in the next video !! :D :D :P @Brian Douglas
Hello Brian, I 've been checking with a low-pass filter of Butterworth and it does not result the same than what you show here. What I did was changing the W at 1%, 50% and 75% and there was no effect. Can you help me. Maybe can I send you my code of Matlab?
