This could be a wonderful lecture and I sincerely appreciate the time and effort Mr. Lum has put into making this video. However, it would be so much better if he transcribed his notes onto the board BEFORE he started talking. Not having to frantically scribble while frantically talking and obstructing a view of the material would be a big improvement. Even better, would be for him to narrate over Power Point versions of his notes. Aside from that, he explained the material quite well.
This is a fucking great lecture. Although the pace is fast, it's at the suitable speed for us to capture what you're saying. I need a lecturer like you in my college life.

Hello, Thanks for this nice video, Can you please clear one of my doubt, You mentioned that At ku there will be Neutral stability, but for a system like y_doubledot + ydot=cos(t) the response will be unbounded, So I think instead of saying at ku means neutral stability it will be more good to say that ultimate gain is the one for which the system poles coincide with the Jomega axis and depending upon the input the system may attend neutral stability. Correct me if I'm wrong anywhere. Hoping for a respsone.

Great explanation! What I was wondering about is the use of the ideal algorithm with the results for Kc, Ti and Td. Should this not be the series algorithm, since it was more common in the days of Ziegler and Nichols? I have not been able to find any confirmation on this. Maybe you can shed your light on it?
AE511: It looks like this technique could be used when you don't have a model of the system which is awesome! I suppose that means you could deploy this technique with any black box where technical documentation of the plant may not be available.

Hello. Is possible to obtain the period, TU (the 1.9), at marginally stable, using equations or formula? and not measuring the period from a simualtion? thanks
At 20:16 a text-comment was highlighted, showing the expansion "s^2 + 6*s^2 + 11*s + 6". I know it was commented out anyway, but it was meant to be cubic with the first term, right?
AE511. Is there a good rule of thumb when picking a "low" Kp at step 1? Or do you need to have some knowledge of your system dynamics? Also when you showed the Matlab plot of all of the different responses plotted together, how come the "no overshoot" configuration still seemed to have some overshoot?
Brad, that is a great question. "Low" is a completely subjective adjective and depends on your system. The "No Overshoot" control type also is not guaranteed to provide no overshoot for all systems. This is one of the major failings of Ziegler-Nichols. It is a sort of back-of-the-envelope approximation. If you need to guarantee no overshoot then you need to do something more mathematically defensible like root locus.
Thanks for the great explanation Sir And, I want to report some error at the tabel 11:32, about the KD value on "some overshoot" and "no overshoot" cmiiw
Thank you for the lecture and the examples with an existing model and no model/experimental data. For cases where we don't have a model, is the process of obtaining K just a simple trial and error? or is there any way of narrowing down to some range of possible K values?
Unfortunately without a model, trial an error is about as best as you can hope for unless you have some physical intuition/insight about the system. If you don't have a model then perhaps a simulation/approximation would suffice?
AE511: In industry or academia if there is a situation that would be well suited to Ziegler-Nichols where this is no mathematical model for a system but the response can be measured, is the typical approach to create an approximate mathematical model to enable one of the higher fidelity PID design techniques you mentioned?
Correct, the typical workflow is to get the model first which allows the linear analysis tools to be brought to bear. Ziegler Nichols is if you are too lazy to get the model

AE511 - The DC motor demonstration was superb and the use of pop ups to show the full table gives a great detailed view.
Alan, great, I'm glad it was helpful. It was fun to get the system working to film this.
I appreciated the DC motor example. It was a helpful visualization.
