I am studying in one of the best engineering University of the world and our Professor wasn't able to deliver the concept as you did. I really appreciate your work kindly keep clearing our confusions.
If the steady-state output of the system is 5 V for a 2-V step, then the DC gain of the system is indeed 2.5. That, however, doesn't necessarily mean the controller constant K is 2.5.
good video. one question about canonical form though, at the end you say it would be incorrect to take the gain from the transfer function of 1/(0.5s + 0.5), but isn't the canonical form 1/s+a rather than 1/s+1 suggesting that you would need to look at another term to find the canonical form
In the video the canonical form is given as K/(tau*s+1) ... so for the transfer function 1/(0.5s+0.5) some students think the DC gain is K = 1 and the time constant is tau = 0.5. This is incorrect. In reality, you need to divide the numerator and denominator by 0.5 to get it into the canonical form, 2/(s+1). Therefore, the true DC gain is K = 2 and the true time constant is tau = 1.
Hello sir, i have watched maximum all of your videos, i was wondering that can you upload a video regarding "how to convert non linear equation to linear equation."
I am not sure what you mean with your question, but you can use the initial slope of a first-order step response to estimate the time constant. If you look at the figure shown around 23 minutes, it shows that the initial slope equals 1/time constant (if you extend the line, it crosses the steady-state value at time t = time constant). Alternatively, I tend to look at the time it takes to reach 63.2% of the total change since I think it is less sensitive to error.

u graduated by now
Software engineer at GM 😊
A 2013 video, still very useful in 2021. Thank you!!
I agree! Am taking control systems 1 right now and very useful!
Still useful in 2024!
im watching in 2024 too.
I'm so thankful to people like you. Very well explained. Can't thank you enough
Very flawless teaching .. I understand every part of it ..
Nice! Thank you for this. I'm currently taking Control Systems 1 and these are very useful!
bro u solved my life with your explication
great work Dr. Rick Hill , thanks a
lot
excellent thank you. The series is very good. I wish my lecturer was as good at explaining things as you.
Thank you. This video is very helpful. The content is well explained.
great video it helped make a few things clearer, explained very well!
Remembering the U, thanks good explanation !!!
you have saved me .... thanks man .. hope u the best
Thank you very much , helped me to resolve my confusion.
this helped a lot for me. thanks for the precisely performance
Thank you for this insight it has been very helpful
Excellent lecture thanks
Good Video, help a lot, many thanks.
Hello, I have a system where the step input is 2v, and the output is 5v and a controller constant k, can we say the dc gain is 2.5?

how can i get a TF if my input is a ramp input and i only have given th
e graph?
Great videos
Hello sir, i have watched maximum all of your videos, i was wondering that can you upload a video regarding "how to convert non linear equation to linear equation."
can you help me? how do you determine the value of tau
great video! nicely done.
oh gaud, life saver!!!!!!
waaaaay better than my garbage teacher
very helpful ,thanks
Is it possible to access the presentation sir
Try this link: www.dropbox.com/s/u7k7cf24md4zx1r/Slides.zip?dl=0
nice video !! thk guys
what is significance of initial slope
I am not sure what you mean with your question, but you can use the initial slope of a first-order step response to estimate the time constant.
