could you please say why the number is exactly 0.632? how do we get it?

Here is more information on why 63.2% apmonitor.com/pdc/index.php/Main/FirstOrderSystems

What if you are given the time constant, and you’re asked to find the dead time?? But you don’t know t_0.632, however, you know what y equals at that time. But you don’t have a function for y(t)…you just have a transfer function written as “Kexp(-theta*s)/(tau*s+1)”? I’ve calculated K and tau, and all i know is there is a unit step of 10 and it takes 20 minutes to reach the new steady state. And the problem is asking for theta…

Have you ever used a Sine Sweep for system identification?
@apm2 жыл бұрын
That is another great way to generate data for system identification, especially for systems that have fast dynamics.

Please for problem what is true? Teta p = 1,2 or teta p = 2,2?
@apm2 жыл бұрын
For problem #1 it is 1.2 for the delay time. It starts from the step change.

You said the dead time is 1.2 secs and then when calculating for Tau p, you said dead time is 2.2.

Thanks for catching that.

need Schrodinger equation solved by Python. Can you upload for us
@apm7 жыл бұрын
This should help you: github.com/jakevdp/pySchrodinger There are many packages for Python and I haven't tested this one.

thank you, but it does not contain vedio lecture

+Jeyaneepan Kanagaratnam, perhaps you could contact the author of the package if you can't get the details that you need from the documentation.
