Ziegler Nichols PID Tuning Method Using Simulink

This video demonstrates how to design a PID controller Using Ziegler Nichol's method and Simulink.
Note that the exact value of the critical gain or ultimate gain Kc can be obtained using Routh-Hurwitz stability criterion as demonstrated here:. • Ziegler Nichols PID Tu...

While getting sustained oscillations the waveform is in negative axis what conditions need to put get in positive axis

[@WakuWakuUnboxing]

hye, how to make the ziegler nicholas close loops method? for pid controller ?

[@usmanagani7496]

sir, how can we apply to control the induction machine 3 phase?

[@amniaalhammadi8017]

What if I do the same and I get a response that has only one peak and it then stabilize? Is this meet the expectation of the PI response?

[@HigherMeditations2007plus8]

It depends on your desired response when designing the controller. If a single peak is what you want then you have achieved your objective.

[@alongkotphoosangad9882]

I maybe say like these, Advantage of it is easy to be used and final value is satisfied, Disadvantage of it is so waste time to find kpu which does y(t) oscillate and still stable, then obtaining ultimate kpu and use it to find kp ki kd but output y(t) with PID Gain from here is high overshoot, however I like your demonstration, thank

[@HigherMeditations2007plus8]

You can still use Routh Hurwitz's stability criterion to determine the value of the critical gain Kp but it's still time consuming.

[@WakuWakuUnboxing]

Hye , is the consider value 20/(s^3+15s^2+10s) the standard design value derived by Ziegler and nichols for estimating PID controller parameters?

[@HigherMeditations2007plus8]

Kindly rephrase your question, it's not clear.

[@WakuWakuUnboxing]

@@HigherMeditations2007plus8 the value 20/(s^3+15s......). Where that value came from.

[@HigherMeditations2007plus8]

@@WakuWakuUnboxing Oh yeah that's a transfer function I used just for demonstration on how to design the PID controller.

[@zenianggara4958]

Sir, where did you get the values 0.6, 0.5 and 0.125 ?

[@HigherMeditations2007plus8]

Hello, those are standard design values derived by Ziegler and Nichols for estimating PID controller parameters.

[@sanju5634]

What is the use of ziegler nicholes method, when we have to change the Kp, Ki, Kd values by ourselves for the desired output?

[@mohammadaminsameti3122]

It's a starting point.

[@HigherMeditations2007plus8]

It gives you reference values to further fine tune your design.

[@gabrielgelencser6366]

Hello! Ziegler-Nichols tuning can we use P/PI/PD?

[@HigherMeditations2007plus8]

Yes you can, depending on your desired response.

[@surajshewale7732]

How do we select transfer function of any system?

[@hakandaglagan9093]

Is there any other method to find K_critical rather than trial?

[@HigherMeditations2007plus8]

You can use Routh-Hurwitz stability criterion.

[@stephanelliott4129]

do the have the rest of this video? Or can you just add the rest of the tuning notes in the comments?

[@HigherMeditations2007plus8]

Greetings, there is really not much more, you can just vary the PID parameters and check that the response meets your specifications.

@@HigherMeditations2007plus8 ok thanks.

@@HigherMeditations2007plus8 Sir , could you provide me you ? i have question on ZN method. can we apply this method when the step reponse curve has overshoot ?

[@HigherMeditations2007plus8]

@@pengyoucn7847 Yes you can, as you can see system for which the controller is being designed has an overshoot.

[@shishirpatil786]

what amount of step value have you given sir

Please use audio in your video. Otherwise it's seems to be monotonous.
