modulated model predictive control of an inverter
I am simulating the attached paper on modulated model predictive control. I have done everything as in the paper. Can some please tell me about my mistake? I am so frustrating since two weeks. Thanks&Regards, G.Sivakumar.

Hi, I changed now. everything is fine.
Is the model finished already? The outputs of the two models uploaded here do not seem to be ok.
I didn't go to great lengths, but the thing that stood out to me was the load resistance and inductance values didn't match that of the R and L values in the predictive controller algorithm.
If I understand correctly, these values should be close so that the controller predictive model is accurate.
Changing the values of the load resistance and inductance to match that of the controller changed the output dramatically:
Phase A Current with Matching Resistance and Inductance
Phase A Current with Original Resistance and Inductance
thank you very much Greg Wolff
P.S. - I'm not sure this constitutes "matching the results of the paper". Hopefully it gets you pointed in the right direction.
Is this model working correctly? Because I can see at the output, Vabc, there are only two phases apparent and they are 180 degrees out of phase. Maybe the third phase is coinciding with one of the other two or it is being switched to short circuit all the time. The magnitude of these two apparent phases are not identical neither. Could there be something wrong with MMPC in general?
