can we generate C/C++ code for closed loop Autotuner?

Hello there,

I am using cloded loop Autotuner for motor controller application. I want to know that, can we get C/C++ code for simulink model "Closed loop PID Autotuner"?

If 'Yes' than how?

Thank you!!!

Yes. If you look at the bottom of https://www.mathworks.com/help/slcontrol/ug/closedlooppidautotuner.html you can see C/C++ Code Generation under Extended Capabilities.

Let me answer the "how" part of this question. There is a documentation page about the complete workflow of using the Closed-Loop PID Autotuner block in real time:

https://www.mathworks.com/help/slcontrol/ug/pid-autotuning-in-real-time.html

You can try the workflow using another example: https://www.mathworks.com/help/slcontrol/ug/tune-pid-controller-in-real-time-using-closed-loop-pid-autotuner-block.html

Since there are usually multiple control loops in motor control, you may want to start with tuning one controller at a time.

Besides directly generating code, you can also run the autotuning algorithm on hardware using External Mode. Here is the relevant documentation page: https://www.mathworks.com/help/slcontrol/ug/control-real-time-pid-autotuning-in-simulink.html

You can try the external mode workflow by referring to another example about Open-Loop PID Autotuner: https://www.mathworks.com/help/slcontrol/ug/tune-pid-controller-in-real-time-using-open-loop-pid-autotuner-block.html
