I was strugling to start with the PID using matlab. But this helped a lot

😊

[@sciencecomplex6605]

The funny thing is that when I try to optimize the PID parameters using the Meta-Tuner software for the transfer function shown in your video , it gives me the following optimal parameters:
Kp = 100000
Ki = 100000
Kd = 100000
for a simulation time of 0.9 seconds
The error is so so small with no over/undershooting .. You can check this controller setting and compare it with that of the Ziegler-Nichols method :)

Hi! Can I use Ziegler-Nichols Method via Matlab Simulink?

[@user-yb2hq3km7h]

very nice! but in the end the steady state value is way different in the begining it's 0.01 and then becomes one, why is that, how can we fix it?

[@100MillionThoughts]

For a step input desired steady state response should be close to one with 2% tolerance band.

[@utilizator1701]

Because it has been implemented a regulator with an integrative component. The integrative component makes the steady state value equal to 1 if the input is a step.

Plz send the link of your reference paper to me.

[@torresautobotsoldier]

so how do you find Ti Td?

[@soumiahafsa1444]

Svp
Comment trouver le gain ???

s'il vous plaît regarder la vidéo complète, tout est clairement expliqué

Thumbs down. First ZN is an inferior method for tuning a system. Second, you make it easy by choosing an easy plat with two real poles at -10 and no dead time.
