How to tune PID controllers for BLDC with SVPWM and vector control?

10 views (last 30 days)
Hello, I need to develop BLDC model with SVPWM and vector control using 3 pid loops (controling for position, speed and current). I've already built the model to controlling for speed but my PI controllers do not work well when I try to control speed. Can anyone explain me where I wrong? I have attached screenshot and my model which includes motor model, PID controller blocks, SVPWM generator and Park-Clarke transformations.

Hi,
I won't be able to troubleshoot your model. However, please take a look at this example we have put together that shows the recommended process of tuning BLDC control loops .
