Closed-loop parameters identification
显示 更早的评论
Hello everyone,
I have a complex simulink model with two PID controllers which must be tuned to make the entire system as similar as possible to the beahviour of a real model.
I have the input and output data of the real model and I want to perform a closed loop identification to tune the parameters.
To be honest, I have no idea how to perform closed loop identification in simulink, so I would really appreciate if anyone could help me.
Thanks
Andrea

I see. You need the mathematical model to perform tuning on the PID. Since the Simulink model is available, you can try using the tools (linmod or linearize) to extract the linear state-space model around operating point. See examples:
