Simulation of PMSM Current Control using FCS-MPC

Hi everyone

I'm trying to control a pmsm current using finite control set MPC, when I'm using PMSM model in simscape everything is fine and currents can track id and iq (currents in dq reference frame) but the problem is PMSM model is based on modified park transform (90 degree behind phase a) and our calculations are based on the original park.

when I change the PMSM model park transform to original park, the results change and FCS-MPC does not work properly.

does anybody have this problem?

Thank you in advance

can you send the simulation and the script please????appreciate! [e-mail].

Hi Hossein,

It sounds to me the rotor angle definition of PMSM isn't aligned with your control algortihm where the Park/Clarke Transform on the dq-axis. I would suggest first check the current signals to the "Park Transform" block as well as the "Clarke Transform" block from the current measurement signals.
