Alan, great, I'm glad it was helpful. It was fun to get the system working to film this.

I've seen Ziegler-Nichols previously but this is a much better / straight-forward explanation

I appreciated the DC motor example. It was a helpful visualization.

first PID tutorial i can understand, ty.

You deserve heaven, this video helps a lot

1:46 "allow you to do this in iterative online fashion" This guy really knows what I'm doing in this year,,,

Thank you for the enlightening discussion. I was looking for a little guidance on tuning my PID for temperature control. Can't wait to get to the lab in the morning... Thanks again!

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.

good lecture. thank you a lot for your sharing, it is helpful

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?

Haha, I forgot that you probably remember that from a few years back. I seem to remember that your system worked great.

thanku sir, your video may help me designing PI controller for bidirectional buck boost charger.

thanks a lot

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.

I implemented this method with Visuino and also auto tuning , and managed to fit this code on a Arduino Nano. i have also wrote the code for ESP32.

Great explanation man. Please can you give us the reference that you have used to obtain the required information, especially the pid table Thanks in advance

AE511: The example with the wheel in the lab was a cool practical application. What were you using to read that data into MATLAB and plot in real time? Thanks!

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.

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 so much for all your efforts! it is really helpful. But Matlab says that "ZieglerNichols" is unrecognized function . How can I solve this problem?

Hi Christopher Lum! How do you know what family of PID controller in terms of P, PI or PID controller to choose depending on a system. What do you base your choice on?

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?

@ChristopherLum

5 жыл бұрын

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?

Are Ku and Pu values same for all the controllers like P, Pi and Pid or different for different controllers

I have a question for you. I wonder how we can calculate without guessing the value of parameter Kp? I want to do PID controlor design with Ziegler Nichols for 2DOF quarter car model. Should I do these steps for both transfer functions? Thank you so much, I am learning Control Theory with you. Appreciate that🙏🙏🌸

this was very informative sir, is there a platform that one could inbox you in?

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

Hi, thanks for this video!, may i know what is the difference between Lambda tuning and Ziegler Nichol's tuning? Why in Ziegler Nichol's we need to make it oscillatory (neutral stability) in order to be able to solve it?

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?

Ki=Kp/Ti for me does not seem to be equivalent to 1.2 KU/TU. There is offset of 0.03. Is this normal or am I doing something incorrect?

AE511: @27:08 your "No overshoot" curve looks like it has some overshoot...?

Point of confusion for me @20:06 on line 10 of the algebraic expansion you have "s^2 + 6*s^2 + 11*s + 6"... should not that first term be s^3 ??

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?
