I did a PMSM FOC simulation comparison over Multisim PMSM model VS mathmetic dq PMSM model, but the Multisim PMSM model based simulation is totally out of expectation, who can help to analyze it?,

Please find the attached, IIn the comparison, I just changed the mathmetical dq PMSM model into a Multisim PMSM model, the FOC part code is still the same as the NI PMSM FOC example. But the results are totally different. I have tried to adjust the PI parameters for the Mutisim based simulation, however, no matter how I changed these parameters, the simulation result is just out of expectation.

I'll investigate.

Thanks a lot, and hope to receive your solution as soon as possible...
