I am trying to limit the DC current of a battery in an foc controlled drive.I implemented a DC Pi cascaded to the id iq pi and the iqref is controlled by this PI.However I am getting oscillations in the DC current with this implementation.Is there any way to limit DC Current within the FOC loop itself so that the dynamics of another PI doesnt cause disturbances in the drive and power is limited smoothly.What is the relation between id iq and idc?

Hello @PRATHEESH S,
There might be many reason for getting oscillations in DC current. If possible, can you please share the simulink model file? It will be helpful in suggesting an appropriate workaround.
