I am trying to implement Field oriented control under field weakening condition for PMSM motor. Manually setting value of Id to negative values, I am getting desired results of speed and Torque but when i try to use MTPA Controller block, speed always get negative to certain RPM and then saturates (see image below). I have attached images of parameters used in MTPA and Motor block, please help me in following what I am doing wrong and how to resolve it. P=0.05 and I = 4 for all PI controllers here i used.
