PI Tuning for Field Oriented Control

Hi everyone, i'm trying to simulate a drive system with induction motor. In my modell I will use one PI controller for speed and 2 PI controller to regulate id and iq seperately. I have been looking for a method to tune the gains of these controller since a week, but I still don't find anything, that help me quikly to solve this problem. I'm very thankful, when someone can give me some advice about tuning the gains of this modell.

Hi hcuong,

I could find a page from MathWorks which has resources for learning how to automatically tune PID controller gains. Link to this page is here

The page mentioned above has very nice videos and examples of PID tuning. I guess you can extend the same workflow to PI controller tuning as well.

Hope this helps,

Cheers!

Hi Abhiram, thank you for your advice. I have already tried to tune PI gains after this instruction, but it still doesn't work. But, I think it is the useful way to tune PI controller in Simulink systematically.

Hard to answer your question without knowing what you already tried and what specifically does not work. Can you post your model and detailed description of what you did?

Thanks very much for your consideration. After checking my model again, i have corrected some errors and then the model can function as expected. But I have just tried it with manual PID-Tuning. My Model was built with power electronic components, so, it may take so much time for me to learn how to tune PID-Controller with Tool in Matlab.
