Hi,
I am trying to use Simscape to block a FOC current controller for PMSM motor. I set the reference Iq current to be 100 A and Id current to be -20 A. Although the Iq current can follow the expected value, the Id current keeps decreasing after suddenly reaches -20 A (see the figure). All the model parameters are the same as the MATLAB tutorial about PMSM (https://www.youtube.com/watch?v=lP4jbmthiyc&t=930s). The model in this vedio can have a good current control, but my model cannot (even though all the parameters are the same).
I appreciate it very much if you could help me out.

The decoupling control is not quite correct for the PMSM motor you are using. You need to insert a multiplier by the number of pole-pairs on the speed. See the picture below.
