Field-Weakening Control with MTPA

Hey Community,

I am trying to implement Field-Weakening Control with MTPA

As this example https://in.mathworks.com/help/mcb/gs/field-weakening-control-mtpa-pmsm.html supports QEP encoder sensor. How to integrate this example with Hall sensor. What paarmeter needs to change.?

Additionaly how to update PID tuning parameters.

Thanks in advance.

Hi @Bhagyesh,

To implement Field-Weakening Control with a Hall Sensor for an Interior PMSM, you can follow the changes outlined in the example of Field Orientation Control using a Hall Sensor with respect to a QEP sensor at the following link, which includes calibration and control logic changes:

https://www.mathworks.com/help/mcb/gs/field-weakening-control-mtpa-pmsm.html

For fine-tuning the PID in the example, you can adjust the “Discrete PI Controller" blocks. For more information on that, refer to the following documentation:

https://www.mathworks.com/help/sps/ref/discretepicontroller.html

Hope this helps!

Thanks @praguna manvi for your answar.

I am following the same link for FWC. I wanted to understand how hall sensor is configured as interupt in this example? https://in.mathworks.com/help/mcb/gs/foc-pmsm-using-hall-sensor-example.html

Do I need to follow the same as an interupt or just adding Hall Validity block, Hall speed and Polistion block in FWC example?

Awating for your valuable feedback.

Thanks.
