Field-Weakening Control (with MTPA) of PMSM

Hello,

I would like to plot the MTPA curve in Matlab. For this I would need the code.

Has anyone of you already plotted this curve?

Many thanks in advance!

Greeting,

Michael

Hi Michael,

Are you referring to the MTPA trajectories based on fixed PMSM parameters ? If so, we now have a block in Motor Control Blockset named "MTPA Control Reference" that will generate the MTPA trajectories based on your motor's parameters. See the documentation for that block below:

https://www.mathworks.com/help/releases/R2022a/mcb/ref/mtpacontrolreference.html

If you are looking at plotting MTPA trajetories based on measured nonlinear torque/flux linkage tables, I could possibly help you come up with some MATLAB scripts once you are able to show me some data.
