Hi,
I am working on implementation of real time close loop control on dsp TMS320F28379D, for synchronization of voltage source converter with single phase grid.
after built the control model and then run the host simulink model, switching signals are generated but output dc link voltage does not track to referance dc link voltage. and there are not effect of change of referance dc link voltage on host model. please provide me solutions to rectify this kind of problems.
Thanks,

A possible issue may be that the controller, I assume a PI, has quickly saturated and the controller is not tracking anything. This might be a consequence of improper reading/scaling of feedback signals, different sampling in simulation and real time system, or task overrun on the microcontroller.
