I want to apply mtpa and field-weakening control in induction machine. there are not any examples with this issue regarding induction machine except one: 'mcb_acim_foc_qep_f28379d'. it must work in field-weakening region too, but it does not, and the results are not acceptable.

Since I want to use this example for my case, I really appreciate if someone helps me.

Thank you!

Hi Fatemeh,

There are some nice shipping examples for MPTA field-weakending control from Motor Control Blockset.

Field-Weakening Control (with MTPA) of PMSM - Example

In order to design the MTPA for induction machine, you can modify this example by replacing the 'Inverter and Motor' part with the example you referred to(mcb_acim_foc_qep_f28379d).

Best,

Christine Li

Hi Christine,

Thank you for your response.

I checked that example, but the equations for PMSM and inductions machine in MTPA method are different (different conditions in optimizing). So, I cant use those blockes for my case.

Thank you

Best,

Fatemeh
