MATLAB: How to tune the PID parameters of the PMSM Field-Oriented Control block

Question

How can I tune the PID parameters of the PMSM Field-Oriented Control block?

I can use the auto-tuning feature in Simulink to tune regular PID control blocks, but I cannot figure out how to tune the PID parameters of the PMSM Field-Oriented Control Block.

I tried tuning the parameters by hand, but this takes too long and produces unreliable results.

Answer 1

Since the PMSM Field-Oriented Control Block is an advanced controller that is not supported by the auto-tuning workflow, there are currently limited options for tuning the PID parameters.

You can perform a parameter sweep or try using the Autotuner blocks to speed up the process of manually tuning the parameters. Here are some topics that may help you tune your controller.
