Problem with PID tuning

Does the automatic PID calibration system work on Simscape?

[Shivam Ahuja]

In order to assist you better can you please tell me about your expectations, what is meant by "on Simscape"? and what is meant by "automatic PID calibration system"?

[Rosario La Regina]

I am building a pendulum using Simscape multibody.I simulated its inverse dynamics and to have desired law of motion I opted for a PID control.

I noticed that using the Simulink PID block it is inpossible to perform an autotuning. I've also seen some tutorials using this command for models created with Simulink only.

My expectation is to obtain by tipuning the values through which my sustem behaves as a given reference.

Currently I have managed to obtain values but threy are not efficient as the law of motion is completely different.

Hi Rosario La Regina

Can you post the mathematical model of the pendulum dynamics? It would be helpful for analyzing the dynamics and stability before attempting to design or tune the controller.

hello there

maybe you should look at some publications, they will guide you to some reference PID tuning
